FOREWORD 

IN WRITING these instructions we have en- 
deavored to include such details as are necessary 

to the successful operation of the Thompson 
Type Caster. A careful study of the description and 
functions of the various parts of the machine by the 
operator is essential. 

The paragraphs relating to the care of the ma- 
chine, adjustments, oiling, cleaning, etc., should be 
read frequently so as to insure a thorough under- 
standing of these principles. 

We are glad to assist the users of the Thomp- 
son Typecaster and will always be glad to answer 
questions, but it is suggested that before inquiries 
are sent to us that these instructions be carefully 
studied to ascertain if the difficulty being encoun- 
tered has not already been discussed herein and the 
remedy provided for. 

In ordering repair parts always give the name 
of the piece and its number appearing in this book. 
When any part of the machine is sent to our factory 
for repairs, attach a tag to it, containing the owner's 
name and address, as a means of identification. This 
is necessary to enable us to return the part to the 
owner. The correct wording of an order will often 
save considerable correspondence and unnecessary 
delay as well as annoyance to our customers. 

This book is prepared for the use of the operator 
of the Thompson Typecaster, in whose possession it 
should be. It cannot serve the purpose for which it is 
intended if kept in the office or on the foreman's desk.

The Machine and Its Placing 

The Thompson Typecaster occupies a 
floor space of twenty-seven by thirty inches. 
When the Lead, Slug and Rule Equipment 
is attached an additional space of twenty- 
four inches is required on the left hand side 
of the machine. The weight of the complete 
machine fully equipped is 750 pounds. 

It is important that the machine be placed 
near a window in such position that the 
light will fall on it from either the right or 
left side of the operator as he faces the ma- 
chine. If placed so the operator must work 
with his back to the window, he is obstruct- 
ing the light. If he works with the machine 
between himself and the window, the light 
will not fall upon the Mold, Matrix Carrier 
and other working parts which it is neces- 
sary to watch at all times in order to insure 
perfect material. The light on a bright day 
falling into the operator's eyes will affect 
his efficiency. 

When artificial light is used (whether gas 
or electric) it should be so placed that it will 
fall directly upon the mold and Matrix Car- 
rier from overhead, but low enough to well 
light up the working parts without shining 
into the operator's eyes. 

The machine should be placed upon a 
solid level surface and firmly fastened to the 
floor. 

Water Connections 

Make water connections as shown on 
"Installation Sheet" on preceding page. 

The Thompson Mold is water cooled 
which quickly cools the metal after it has 
entered the mold chamber. It is important 
that all water connections be made so that 
the flow of water may be easily regulated. 

The water supply pipe to the machine 
need be no larger than quarter inch iron 
pipe. A good lever handle stop cock which 
will not leak should be provided and con- 
nected to the end of the supply pipe so that 
it will be convenient for the operator to 
regulate the flow of water as required with- 
out leaving his position in front of the ma- 
chine. A piece of good rubber tubing should 
be used to connect the stop cock on the end 



of supply pipe with the large inlet pipe on 
the mold. 

The quarter inch waste water drain pipe, 
which extends about three inches beyond 
the back of the machine top base, should be 
connected directly with a three-eighths-inch 
iron pipe. This should be run into a drain 
so the waste water will run out without any 
attention from the operator. 

When casting type of the small bodies 
only a little water is required to keep the 
mold cool, but when casting the larger sizes 
of type, a good flow of water is necessary 
to keep the mold sufficiently cool to insure a 
maximum casting speed. 

The speed of casting type on the Thomp- 
son Typecaster is limited only by the length 
of time required to fill the mold solidly with 
metal and cool it sufficiently so that it may 
be discharged easily. 

Electric Connections 

The motor, which is installed in the base 
of the machine, when direct current, is 
wired to the snap switch and rheostat which 
are located on the right hand side of the 
machine. 

When alternating current single phase 
motor is used it is wired to the snap switch 
only. No rheostat is required for alternat- 
ing current. 

When motor is two or three phase alter- 
nating current it is placed in position in the 
machine base, but all electrical wiring must 
be done by the customer when the machine 
is installed. 

In making the electrical connections, a 
standard knife switch with a cutout for "no 
arc" fuses should be placed on the wall near 
the Typecaster so that the current may be 
cut off from the machine whenever it is not 
in use. The local Underwriters' or Insurance 
Rules for wiring should always be complied 
with in making electrical connections. 

Gas Burner and Connections 

Gas Connections with the machine should 
be made as shown on Installation Sheet. 

The Gas Burner (H-599) for heating the 
metal is so constructed that the flame will 
spread, thus heating the metal evenly with 



THOMPSON TYPE MACHINE COMPANY 



a minimum amount of gas. The flame should 
be blue ; if it is red it will deposit soot on 
the bottom of the Melting Pot (H-571), 
which prevents the metal from becoming 
properly heated. The air-supply regulator 
on the lower end of the air mixer may be 
turned to the right or left to open or close 
the holes through which air passes into the 
mixer. Too much air will cause the g*as to 
ignite in the mixing chamber ; if that occurs, 
the gas must be turned off and the air holes 
closed up a little more before again lighting 
the gas. When the flame is blue it generates 
the most heat and once adjusted it requires 
no further attention, unless the gas-pres- 
sure should vary greatly. 

A good supply of gas is essential. Noth- 
ing smaller than a three-eighths-inch gas 
pipe should be used to supply the Burner. 
The gas cock should be large enough to 
supply a free flow of gas through it to the 
burner. After the metal is melted the gas 
may be turned down so the metal will not 
be overheated but kept at an even tem- 
perature. 

The average amount of gas consumed to 
heat and keep the metal at the proper tem- 
perature is 275 cubic feet in eight hours. 

Gasoline Burner and Connections 

A Gasoline Burner (H-844) is furnished 

for use where gas is not available. This 

outfit consists of a Gasoline Pressure Tank, 

■(E-844-B), Pump (E-844-C), Burner (H- 

844), and 10 feet of hollow wire (E-844-A). 

Place the Tank as far away from the 
Burner as the length of the hollow wire will 
permit. Fasten one end of hollow wire to 
tank valve marked "Gas" and the other end 
to connection on Gasoline Burner. Close 
Gas Valve with hand wheel on Burner and 
valve marked "Gas" on Tank. Now remove 
the Filling Plug from the Tank and after 
rilling the latter one-half full with gasoline 
screw the plug back tightly. Open valve on 
tank marked "Air" and pump air into Tank 
to about 10 pounds pressure, then close air 
valve. 

Now open Tank Valve marked "Gas"; 
then open Gasoline valve in Burner. Allow 



gasoline to drip until it fills Generator Pan 
underneath the Burner. When Pan is full 
shut off gasoline at the Burner. Light gaso- 
line in the pan, allowing it to burn until 
flame dies out, then open Gas Valve and 
light Burner. The flame must be blue to 
generate the most heat ; if the flame is not 
blue it proves that the proper mixture is not 
being obtained. In that case, the Needle 
Valve, the head of which projects below the 
bottom of the Generator Pan, must be ad- 
justed until the flame burns blue. 

In case the Burner "back fires" it indicates 
that the Needle Valve is open too wide and 
needs adjusting. 

Kerosene Oil Burner and Connections 

To successfully burn kerosene for the 
greatest amount of heat it is necessary that 
the fuel be changed into a vapor, then mix- 
ed with a sufficient amount of air and finally 
burned so that the flame is distributed over 
the surface to be heated. Properly gener- 
ated, and mixed with the proper amount of 
air, the fuel burns with a blue flame and 
gives off intense heat. The Ozaukee Burner 
develops this intense heat when used in 
accordance with instructions.

Attach the Burner to the Bracket pro- 
vided for it under the Metal Pot. 

Attach the handle to end of needle valve 
and lock with lock nut by holding the lock 
nut with plier and turn handle to right until 
tight. 

Attach one end of the hollow copper wire 
to the end of the Generator and the other 
end to the valve on the Tank marked "Oil." 

Unscrew the filler cap on the tank and fill 
about three-fourths full. Close all valves 
and filler cap. 

Attach pump and open air valve. Pump 
air into the tank until the gauge registers 
35 to 40 pounds. You are now ready to 
generate gas. 

# * * * 

When the burner is cold the generator 
must be heated by application of outside 
heat. For this purpose you will find two 
generating cups, a small one fastened to the 
heel of the generator and a large one direct- 



THOMPSON TYPE MACHINE COMPANY 



ly under the generator. Fill the cups two- 
thirds full of denatured alcohol and ignite. 
Under no circumstances use gasoline in 
place of denatured alcohol. 

Caution 

Be sure to have the needle valve on bur- 
ner open four or five turns while generat- 
ing. This valve is used to regulate flame 
and clean out jet orifice only. 

After alcohol in large cup has almost 
burned out burner is ready to light. The 
flame from the cups will ignite the vapor 
as it comes through the top of the burner. 
Turn on oil valve on tank very slowly, not 
over a quarter turn or less to start with un- 
til the burner has caught itself. Opening 
valve too wide permits too much cold oil 
to rush into the generator, thus chilling the 
generator and causing the burner to burn 
with a yellow flame. The burner should 
light up with a blue flame. If it burns with 
a yellow flame it proves that your gen- 
erator is not hot enough and you should 
shut off the oil valve at the tank and gen- 
erate a little more with alcohol. 

If more heat is required increase the pres- 
sure on the tank, but never more than 40 
pounds. 

To Turn Out Burner 

To turn out the burner close the oil valve 
at the tank. Do not use the needle valve at 
the burner for this purpose. 

To replace any part of the burner be sure 
to send us an exact description of the part 
wanted. If there is any doubt as to the ex- 
act description of the part or parts needed 
we advise that you return to us the part 
that is to be replaced. 

Speed of Main Shaft of the Machine 

When the machine is motor driven the 
motor furnished installed in the base is so 
arranged that the main shaft, which extends 
about four inches beyond the rear of the 
machine (on the inner end of which the fric- 
tion disc is mounted) will run at the proper 
speed. 

If the machine is equipped for belt drive 
the speed of the pulley mounted on the ex- 
tending end of the main shaft should run 
245 revolutions per minute. 



The Cams 

Facing the front of the machine, and 
counting from left to right, the cams on the 
cam shaft have the following actions : 

First is the Choker Cam (G413) which 
operates the Choker Cam Lever (C-523) 
through which the Choker Lever Link (C- 
527), Choker Lever (C-854), Choker Fork 
(C-534) and Choker (C-531) are actuated. 

Second is the Pump Cam (P-510) which 
operates the Pump Cam Lever (P-524) 
through which the Pump Lever Link (P- 
526), Pump Lever (P-537) and Pump (P- 
572) are actuated. 

Third is the Vertical Mold Blade Cam 
(V-509). This cam operates the Vertical 
Mold Blade Cam Lever (V-S25) attached to 
the Vertical Mold Blade Lever (V-512), 
which moves the Vertical Mold Blade (V- 
612) for Linotype Matrices and (V-613) 
for Thompson wide or narrow Matrices, up 
and down at the type discharge end of the 
Mold Chamber. 

Fourth is the Matrix Carrier Cam (N-513) 
for operating the Matrix Carrier Cam Lever 
(G-925) and Matrix Carrier Lever (G-924) 
through which the Matrix Carrier is ac- 
tuated. 

Fifth and sixth are the Mold Body Aux- 
iliary Cam (M-516) and Mold Body Cam 
(M-515), respectively, for operating the 
Mold Body Cam Lever (M-521) and Mold 
Body Lever (M-520) through which the 
Mold Body Plate (M-942) and Mold Body 
(M-894) are actuated. 

Cleanliness 

Cleanliness is absolutely essential in a 
machine required to do the exacting work 
of typecasting. Small particles of metal, 
grit or dirt of every description must be 
kept away from the mold parts especially. 
A soft, clean rag should be used to wipe 
body pieces, etc., carefully before putting 
them into the mold. The matrices and mold 
faces should also be wiped and all metal 
brushed away when matrices are changed, 
and if the run is a long one on a matrix, 
remove the carrier occasionally and wipe 
the parts. The entire mold should be re- 
moved occasionally and drenched with gas- 
oline or benzine and wiped clean, then 



8 



THOMPSON TYPE MACHINE COMPANY 



thoroughly oiled and replaced. Keep the 
oil grooves in the mold free from accumula- 
tions of metal. Run a wire through the oil 
hole connecting the oil pad with the front 
end of the mold. 

When mold bodies and similar parts are 
stored away coat them with Vaseline, which 
is better than oil as a rust preventative. 

Wipe the interior faces of the cams to re- 
move grit and do not allow oil to run over 
the machine surfaces. Keep machine clean 
always and covered when not running. 

Oiling Mold Parts 

The most important thing in the opera- 
tion of any machine is proper lubrication. 
If bearings and surfaces which move in 
contact are not oiled the parts soon become 
heated and carbon is formed, which seizes 
the metals and causes deep cuts in their 
surfaces. A rapidly moving part lacking oil 
will be ruined in a few minutes. 

In a machine of this class it is absolutely 
essential that the mold parts be kept amply 
lubricated, and because of the intense heat 
near these parts the task is the more diffi- 
cult. We have solved the problem with an 
adequate oiling system, but all our efforts 
will be set at naught unless the operator 
puts oil into the cups provided for that pur- 
pose. 

Oil should be supplied at least once an 
hour while running. An oil cup is located 
on the back wall of the mold stand near the 
water tubes and another one above the 
Type Receiving Shoe (A-14). The sight 
feed oiler should be kept full and adjusted 
to feed about one drop a minute. A high- 
grade spindle oil should be used. We re- 
commend the mixing of "Oildag" with the 
oil which we can furnish. It will save the 
mold from cutting. Do not use a heavy, 
thick or cylinder oil. 

Be sure to get the oil into the bearings. 
Oil on the outside of the machine does no 
good; it only collects dust and dirt and is 
an indication of a careless operator. Be 
sure the oil flows freely into the oil holes 
and bearings and, after oiling, wipe off all 
oil that may run out of them. There are 
thirty-four oil holes and two grease cups on 
the machine; be sure none are overlooked. 



Cam Rollers 

Next in importance are the cam rollers. 
If these do not revolve freely on their studs, 
(and they will not unless oiled), they soon 
wear a flat surface at one or more points. 
This causes the cast-iron cams to wear 
rapidly, and the result is that all cam-lever 
movements are affected and their time and 
accuracy destroyed. 

Each of the Cam Levers (G-925 and V- 
525) has oil holes near the Cam Rollers. The 
oil hole for the Pump Cam Lever Roller is 
in the rear end of the Lever (P-524) and can 
be seen only from the back just above the 
Base Top when the Metal Pot is swung 
back and the Pump Stop (P-682) is in posi- 
tion under the Pump Cam Lever (P-524). 
This Pump Cam Lever Roller must be 
oiled frequently through the oil hole to 
prevent the roller from wearing flat and 
consequently cutting the Pump Cam. The 
Mold Body Cam Lever Roller has an oil 
hole to lubricate both rollers on the Lever 
(M-521). Do not neglect these rollers. Oil 
frequently. 

Cam Shaft 

There is one oil hole in each Cam Shaft 
Bearing (K-504 and K-505), both outside 
the base. 

Friction Plate Shaft 

The grease cup above the bearing at the 
rear of the machine must be given a turn 
every day or two. "Gredag" is recommend- 
ed as a lubricant for the grease cups. 

Friction Wheel Shaft ' 
This Shaft carries the fibre-faced Friction 
Wheel and the bearings at each end must 
be oiled frequently. This Shaft requires 
ample lubrication. 

Inside the Base, and mounted on the 
lower side of the Friction Wheel Shifter 
Yoke, will be found a grease cup for lubri- 
cating the Yoke. It should be kept filled 
with cup grease and the cap should be 
screwed down a little every two or three 
days. This grease cup can be reached only 
through the lower base front door.

Speed Change Gears 

Two oil tubes lead to the Shaft on which 
the speed changing gears are mounted. They 
are covered by the swinging plate marked 
"Oil" seen when the top base door is lower- 
ed. There is one oil hole also outside the 
base on the right hand side for the Speed 
Change Gear Shaft. 

Cam Levers 

There is one oil hole for each of the six 
levers mounted on the Mold Stand, the 
Choker Cam Lever (C-523) ; Pump Cam 
Lever (P-524) ; Vertical Mold Blade Lever 
(V-525); Matrix Carrier Lever (G-924) ; 
Mold Body Cam Lever (M-S21) ; and two 
for the Mold Body Lever (M-520), need a 
drop of oil. The segments between the two 
last named Levers should also be oiled. 

Matrix Carrier 

The Matrix-carrier slides (G-670 and 
G-671) can be oiled through the two oil 
holes above them. 

Small Bearings 

One oil hole will be found in the top of 
the Pot Yoke Stud (H-834). 

There is one oil hole in the square end of 
adjusting screw (M-674) connecting with 
the mold-body plate, and one oil hole in the 
top of the mold-body lever (M-520). 

Metal Pot Levers 

Oil should not be used on any of the 
melting Pot Levers as it will burn off and 
cause the parts to stick or cut. For Lubri- 
cating the Pot Levers take two parts mut- 
ton tallow and one part very fine graphite. 
Heat the mutton tallow and mix the graph- 
ite with it. When cold, a small amount of 
this mixture used daily on the Metal Pot 
Levers will keep them in good working 
order. If fine graphite and mutton tallow 
are not available "Gredag" which can be 
purchased from us may be used. 

The following are the parts on which the 
tallow, or gredag, lubricant should be used ; 
Two oil holes at the rear end of the Pump 
Lever (P-537) and one in the center of up- 
per end of the Pump Stem (P-572). One 
oil hole in each end of the Choker Lever (C- 
854). A small quantity on the Pump Link 



Pin (P-706) and the Pump Connecting Pin 
(P-549) where these pass through the Pump 
Links (P-705) ; also a small quantity on the 
connecting Pins (P-544) for the Pump and 
Choker Lever Links (C-526 and C-527). 

If motor-driven, oil the bearings at each 
end of the armature shaft. 

Oil all holes once each day. Mold parts 
and matrix-carrier slides must be attended 
to every hour. 

Electric Pot 

The Electric Pot can be fitted to any 
Thompson Typecaster except Model "E," 
and it follows closely the design of the Gas 
Pot. 

The electric method for heating is the 
most modern; its advantages are many and 
important. It is clean, safe, quick, easily 
controlled and uniform. The temperature • 
is automatically controlled by the Dynamic 
Thermometer and the Magnetic Switch 
which act jointly. The necessity for ex- 
haust pipes to carry off the gas fumes is 
eliminated, and there is an absence of open 
flames and the resultant products of com- 
bustion. 

The output of the Thompson Typecaster 
is increased and the life of the metal is 
conserved by the close and accurate regu- 
lation of temperature, preventing the burn- 
ing out of tin, which is the most expensive 
element that enters into Type Metal. The 
metal is delivered to the casting point at 
the exact temperature registered in the Pot. 
This insures more perfect type and faces, 
and better welds at the joints in strip ma- 
terial, as well as increased production. 

The electrical equipment consists of the 
Electric Metal Pot with its heating units 
incased in the solid iron of the outer wall 
and bottom of the Pot; the Dynamic Ther- 
mometer which is attached to the Pot; the 
Control panel and the Rheostat for control- 
ling the throat heating units. There are 
three heaters in the Pot: one in the right 
side; one in the left side, and one in the 
bottom. These heating units are made of 
"Nicrome" alloy which will not melt be- 
low 2800 degrees Fahrenheit. They there- 
fore have a factor of safety far in excess of 
any requirements. 



Dynamic Thermometer 

The Dynamic Thermometer which auto- 
matically controls the heating of the type 
metal in the pot, is adjusted at the factory 
to maintain the metal within 15 degrees 
Fahrenheit of any predetermined tempera- 
ture. It consists of a metal bulb, tube and 
spring which are filled with mercury and 
absolutely airtight. 

The bulb, the capillary tube, and operat- 
ing coil are filled with mercury and sealed. 
The expansion of the mercury causes the 
operating coil to move a lever toward a 
contact, upon touching which the magnetic 
switch reduces the current. As the temper- 
ature decreases the mercury contracts and 
the operating coil swings the lever back, 
increasing the current. Thus the heating 
current is automatically varied and the tem- 
perature of the metal held within correct 
operating limits. 

To change the temperature, place the 
Mercury Thermometer (H-991) into the 
Metal Pot (H-571) and leave it there long 
enough until the temperature of the metal 
is accurately registered thereon. Then, with 
a small screw driver turn the screw, the 
head of which is located inside the hole on 
the right hand side of the Dynamic Ther- 
mometer Housing, to the right to increase 
the temperature and to the left to decrease 
it. 

Care should be exercised when dropping 
cold metal into the Pot that the pigs do 
not strike against the Mercury Bulb of the 
Dynamic Thermometer, as that might dam- 



age it. 



Rheostat 



The Rheostat controls the throat and 
nozzle heater circuit only. Turning the 
Rheostat Knob in a clock-wise (to the right) 
direction will increase the heat at the Noz- 
zle ; turning the Knob in a counter clock- 
wise (to the left) direction will decrease 
the heat. 

After operating the Electric Pot a short 
time the operator will know in which posi- 
tion the Rheostat Knob gives him the cor- 
rect temperature at the Nozzle. Once he 
has ascertained this he should mark the 
Knob and the Rheostat so that he can al- 



ways set the Rheostat Knob in the correct 
position to give him the desired Nozzle 
temperature. 

Control Panel 

The Control Panel consists of a slate 
panel mounted in a sheet metal cabinet sup- 
porting the following parts of the control : 
The main line fuses which protect the entire 
system from overloads ; the Snap Switch 
which connects the outside line to the equip- 
ment through the fuses and terminals ; the 
Resistance coil and wiring and the Mag- 
netic Switch. 

Cost of Operating the Electric Pot 

To arrive at the cost per hour for operat- 
ing the Electric Pot the following data, 
which is the result of tests made, may be 
used. The size type cast during the test 
was 30 point ; operating temperature 700 
degrees Fahrenheit; time consumed in 
bringing cold metal to operating tempera- 
ture 45 minutes ; electric power consumed 
2*4 Kilowatt hours; average quantity of 
power consumed while machine was casting 
type = 2.03 Kilowatt hours per hour; aver- 
age quantity of electricity consumed while 
metal was kept at operating temperature 
but no type being cast = 1 1/5 Kilowatt 
hours per hour. 

Using the foregoing data as a basis, the 
value of the unit used in any given locality 
can be easily computed and the cost of the 
operation thus determined. 

Wiring Diagrams 

A wiring diagram will be found on the 
inside of the Control Panel Door. All wir- 
ing should be enclosed in flexible conduit 
and the Local Underwriters or Insurance 
Rules should be complied with in making 
electrical connections. When disconnecting 
any wiring be sure to mark it properly so 
it may be reconnected exactly as it was. 
When fuses are replaced care must be taken 
they are of the same ampere rating as the 
ones removed. 

Definitions 

The CIRCUIT is that part of the equip- 
ment which is intended to carry electric 
current, such as copper wires, resistance

wires, switches, etc. They are all insulat- 
ed from the frame of the Pot. 

The CURRENT is the electricity passing 
through the equipment. 

AMPERES is the volume of current pass- 
ing through. 

VOLTS is the strength of pressure of the 
Current. 

A WATT is the product of the volts multi- 
plied by the amperes. 

A KILOWATT is 1,000 watts. 

A KILOWATT HOUR is one Kilowatt of 
current used for one hour. 

A GROUND is a bare part of the electric 
circuit accidentally touching the frame of 
the pot. 

A SHORT CIRCUIT is one or more 
grounds which allow the current to take 
a shorter path. 

An OPEN is an interruption in the electric 
current, such as a broken wire, etc. 

RESISTANCE is an obstruction in the 
electric circuit retarding the flow of cur- 
rent. 

SERIES Connection means that two or 
more units are connected in line with 
each other. Current enters one terminal, 
passes through the windings, out of the 
other terminal and directly into the next 
unit, through its windings and out in the 
opposite side of the line. 

PARALLEL OR MULTIPLE Connec- 
tions means that two or more units are 
wired in such a way that each makes a 
complete circuit of itself. Current enters 
a unit, passing through its windings and 
directly back to the line. 
An electrical circuit carrying current can 

best be simply explained by considering an 

iron pipe through which water is flowing 

under pressure. 

The pipe represents the circuit and water 

passing through it represents the current. 

The volume of the water flowing repre- 
sents the amperes and the pressure of the 
water represents the volts. 

A leak that allowed the water to escape 
would represent a short circuit and a valve 
in the pipe partially closed would represent 
resistance. 



Important 

When a Thompson Typecaster is shipped 
from the factory, the Metal Pot contains a 
very small amount of metal. The first opera- 
tion is to melt down enough metal to fill 
the Pot. On this first heating the Pot should 
be filled with old type or small pieces of 
metal. These will lay closer to the inside of 
the Pot than large ingots or pigs and melt 
down quicker with less danger of overheat- 
ing the heating units, which are not de- 
signed for operation in air, but should al- 
ways be covered with type metal when the 
current is on. 

While operating the machine always 
keep the Metal Pot as nearly full of metal 
as possible to prevent dross and oxides be- 
ing drawn from the surface of the metal 
into the Choker Channel and the Pump 
Well. 

Type Mold Adjustments 

The Mold is equipped with eleven body 
Pieces and three Jet Ejectors for casting 
type, borders, ornaments and high and low 
quads and spaces in the following sizes : 6 
point; 8 point; 10 point; 12 point; 14 point; 
18 point; 24 point; 30 point; 36 point; 42 
point and 48 point. Special sizes are made 
when ordered. 

The entire Mold should be wiped abso- 
lutely clean and must be thoroughly oiled 
and free from accumulation of dirt or metal. 
All Body Pieces and Jet Ejectors, before 
every insertion into the Mold, should be 
carefully wiped with a clean rag. 

There are three sizes of Jet Ejectors, the 
smallest, No. 1, designed to use when cast- 
ing type from 5 to 18 point inclusive, the 
medium, or No. 2, when casting type from 
24 to 36 point inclusive, and the No. 3 is 
used from 42 to 48 point inclusive. 

To Change Jet Ejectors

2, 3 and 4; Mold part numbers, plates 6 
and 7.

rier (A-8) and the Nozzle Plate (H-639) 
and Type Receiving Shoe (A-14). Loosen 
the knurled head Jet Block Adjusting 
Screws (J-650 and J-691), which pass 
through the Mold Stand Cap at both ends 
of Jet Block (A-12), until ends are even 
with the underside of the Mold Stand Cap 
(N-910), Insert the large end of the Pin 
Wrench (E-981) in the hole in the Jet 
Block Adjusting Eccentric (J-897) and turn 
to the right until the Jet Block touches 
the Mold Stand Cap (N-910). This lifts 
the Jet Block Assembly (A-12) so that the 
Jet Ejector may be removed. To remove 
Jet Ejector turn Hand Wheel (S-541) until 
Jet Ejector is at extreme right hand posi- 
tion, then raise Jet Ejector by inserting 
sharp end of Body Lifting Tool (M-982) in 
groove on underside of right hand end of 
Jet Ejector, raising it by a slight down- 
ward pressure on the end of Mold Body 
Lifting Tool. Then take hold of Jet Ejector 
with fingers and remove. To insert another 
Jet Ejector reverse above operation. Never 
change Body Pieces unless a Jet Ejector is 
in place. If Jet Ejector or Body Piece is 
clamped too tightly the parts will slide with 
difficulty and the Body Piece or Jet Ejector 
may become scored. If clamped too loose 
metal will collect between the Ejector and 
the upper and lower Jet Blocks and the type 
cast will be large in body and have a burr, 
Make the adjustment so there is just enough 
pressure to insure the casting of smooth 
type and jets. The pressure of the Knurled 
Screws (J-650 and J-691) must be slackened 
as soon as a few casts have been made and 
the mold is hot to prevent the Jet Ejector 
from becoming scored. 

To Change Mold Body Pieces 

For Machine part numbers see plates 1, 
2, 3 and 4; Mold part numbers, plates 6 
and 7. 

Be sure the Metal Pot is swung away 
from Mold and the Matrix Carrier, the Noz- 
zle Plate and Type Receiving Shoe have 
been removed as in the case of changing Jet 
Ejectors. Then loosen knurled head Mold 
Block Adjusting Screws (M-683 and M-693) 
that pass through the Mold Stand Cap at 
both ends of the Mold Top Block (A-ll) un- 
til ends are even with the underside of Mold 



Stand Cap (N-910). Insert large end of the 
Pin Wrench (E-981) in the hole in Mold 
Top Block Adjusting Eccentric (M-898) 
and turn it to the right until the Mold Top 
Block (A-ll) is brought up against the 
Mold Stand Cap (N-910). Now insert the 
sharp end of the Body Lifting Tool (M- 
982) in groove on underside of right hand 
end of the Mold-Body (M-894), raising it 
by a slight downward pressure on the end 
of the Mold Body Lifting Tool. Then push 
the Mold Body forward toward the left, take 
hold of it with the ringers and remove it 
from the Mold. Wipe new Body Piece and 
mold cavity carefully and insert the Body 
Piece from left hand end of the Mold, push- 
ing it back until it catches into the Mold 
Body Plate (M-942). Before -seating the 
Body Piece, be sure that no dirt or metal 
remains in the mold or prevents the Body 
Piece engaging the Mold Body Plate (M- 
942). Turn the Mold Top Block Adjusting 
Eccentric (M-898) until the Mold Top 
Block (A-ll) is snugly seated on the new 
Body Piece, and then bring the Mold Block 
Adjusting Screws (M-683 and M-693) to a 
light bearing on top of the Mold Top 
Block (A-ll). Turn the machine slowly 
backwards and forwards by hand to test 
the adjustment. It should be snug but must 
not bind. Do not make it too tight. The 
pressure must be slackened as soon as a 
few casts have been made. Never change 
a Body Piece unless the Jet Ejector is in 
place. 

Felt Oil Pads 

To carry oil direct to the Body Piece and 
Jet Ejector the Thompson Mold is pro- 
vided with three Oil Pads. One of these is 
located in the Mold Bottom Block, one in 
the Mold Top Block and one in the Upper 
Jet Block. 

When through long and constant use 
these Oil Pads shrink so they are nr_> longer 
in contact with the Body and Jet Ejector 
they will not properly lubricate the parts 
and the mold may become scored or cut. 

To remedy this the old Pads should be 
replaced by new ones. If new thick Felt 
is not obtainable remove the old Pads, 
clean them in gasoline or turpentine and 
place a little clean waste in the bottom of 



THOMPSON TYPE MACHINE COMPANY

the opening where these pads belong and 
put the old Pads back into place. 

To Change Foot Plow 

When the Jet Ejector (J-893) is changed 
it is necessary to change the Foot Plow 
(T-974). Three thicknesses of Foot Plows 
are furnished corresponding to the different 
thicknesses of Jet Ejectors. Be sure the 
Foot Plow Bracket (T-976) is perfectly 
clean so the Foot Plow will be in proper 
position for grooving the type. The Foot 
Plow (T-974) should be adjusted to cut no 
deeper than just enough to remove the 
rough portion left on the foot end of the 
type where the jet was removed. 

To Remove the Type Mold 

For Machine part numbers see plates 1, 
2, 3 and 4; Mold part numbers, plates 6 
and 7. 

First remove Matrix Carrier (A-8), Noz- 
zle Plate (H-639) and Type Receiving Shoe 
(A-14). Then loosen the Vertical Mold 
Blade Adjusting Screw, the head of which, 
in some models, is located in the end of the 
Mold Stand (N-502) immediately under the 
Type Stick, while in other models it is 
located on the front of the Mold Stand im- 
mediately to the left of the Matrix Carrier 
Slide (G-670). Now loosen the Hexagon 
Nut on the knurled head Upper Adjusting 
Screw (V-684) that passes through the top 
of Vertical Mold Blade Cam Lever (V- 
525), then raise the Vertical Mold Blade 
Lever Yoke (V-511) and slide the Vertical 
Mold Blade Lever (V-512) to the left as 
far as it will go. This draws the Vertical 
Mold Blade Lifting Block (V-615) out of 
the recessed portion of the Vertical Mold 
Blade (V-612 or V-613). Now lift out the 
Vertical Mold Blade. (CAUTION: On the 
right hand end of the Mold Stand (N-503) 
immediately under the Mold (A-13) is the 
Mold Locating Screw (M-983). This screw 
is NOT to be disturbed when the Mold is 
removed from the Mold Stand as it is ad- 
justed at the factory to hold the Mold in 
its correct position in relation to the Matrix 
Carrier). Next loosen the small screw that 
passes downward through the back right 
hand end of the Mold Body Plate (M-942) 
and withdraw the Mold Body Plate Con- 



necting Pin (M-933). This disconnects the 
Mold Body Plate Adjusting Screw (M- 
674). 

Now loosen the knurled head Mold Block 
Adjusting Screws (M-683 and M-693) and 
the Jet Block Adjusting Screws (J-650 and 
J-691), which pass through the Mold Stand 
Cap, until the ends of these Adjusting 
Screws are even with the underside of Mold 
Stand Cap. Insert large end of Pin Wrench 
(E-981) in the hole in Mold Top Block Ad- 
justing Eccentric (M-898) and Jet Block 
Adjusting Eccentric (J-897) and turn each 
Adjusting Eccentric to the right until the 
Mold Top Block and the Jet Block are 
brought up against the Mold Stand Cap. 
Now insert the sharp end of the Body Lift- 
ing Tool (M-982) in the groove on under- 
side of Mold Body (M-894), raising it by 
a slight downward pressure on the outer 
end of the Mold Body Lifting Tool; push 
the Mold Body forward toward the left, 
take hold of it with the ringers and remove 
it from the Mold. Now remove the Jet 
Ejector in the same manner. 

Remove the Mold Body Plate (M-942) 
by drawing it to the right out of its bear- 
ings in the Mold. With the small screw 
driver remove the four Mold and Jet Block 
Lifting Stud Nuts (M-939). Next take out 
the four Mold Stand Cap Screws (N-872) 
and lift the Mold Stand Cap (N-910), with 
the left hand, high enough to enable you 
to remove the Mold and Jet Block Lifting 
Yokes (J-937). 

The Mold can now be lifted out of the 
Mold Stand. Should the Mold fit very tight 
in the Mold Stand care must be exercised 
in removing it, using only a piece of brass 
rod or a hard wood stick for a lever to raise 
the Mold out of its position. Place the 
Mold on the bench and lift out the Mold 
Top Block (A-ll) and the Jet Block 
(A-12). Be very careful not to damage any 
of the parts in doing this; use only a piece 
of brass rod or a hard wood stick for a lever 
to raise the parts out of the Mold. Flush 
all the Mold Parts with benzine or gaso- 
line and wipe them clean; also run a piece 
of wire into the oil hole that runs from the 
front of the Mold Bottom Block (A-9) 
through it to the lower felt pad to be sure 



14 



THOMPSON TYPE MACHINE COMPANY 





oil will flow freely through it to lubricate 
the side of the Vertical Mold Blade (V-612 
or V-613) and the end of the Mold (A-13) 
where they come in contact one with the 
other. 

After thoroughly cleaning all the Mold 
parts wipe them with a piece of clean cloth 
dipped in fine Lubricating oil and assemble 
the Mold ready to put it on the machine. 

To Replace the Mold 

Before replacing the Mold, after clean- 
ing, be sure that all surfaces of the Mold 
(A-13), and that part of the Mold Stand 
(N-502 and N-503) into which the Mold 
fits, is absolutely clean and free from metal 
or dirt. There is no allowance for dirt and 
a slight amount will throw the Mold out 
of position. Take care, also, before replac- 
ing the Mold that the Mold-Top Block 
(A-ll) and the Jet Block (A-12) are not 
raised so high that they prevent the Mold 
Stand Cap (N-910) being screwed down 
firmly. 

Place the Mold into the Mold Stand, 
press it down firmly and push it to the 
right until the lower right hand edge of the 
Mold comes firmly against the inner side 
of the head of Mold Locating Screw (M- 
983). Put the Mold Stand Cap (N-910) in 
position, place the four Mold Stand Cap 
Screws (N-872) in place and screw the 
Mold Stand Cap (N-910) down firmly. 

After wiping it with a clean cloth satu- 
rated with clean oil, insert the Vertical 
Mold Blade and press it down to its lowest 
position. Now release the Mold Stand Cap 
Screws just a trifle and then tighten the 
Vertical Mold Blade Adjusting Screw so as 
to press the Vertical Mold Blade firmly 
against the end of the Mold (A-13), there- 
by forcing the Mold snugly against the 
Mold Locating Screw at the right hand end 
of the Mold Stand. Now again tighten the 
Mold Stand Cap Screws (N-872) down 
firmly. 

Release the Vertical Mold Blade Adjust- 
ing Screw just a trifle, push the Vertical 
Mold Blade Lever (V-512) to the right 
until the Vertical Mold Blade Lifting Block 
(V-615) is in the recessed portion of the 
Vertical Mold Blade; press the Vertical 



Mold Blade Lever Yoke (V-511) down into 
its locked position. 

Now with the Pin Wrench (E-981) 
tighten the Upper Adjusting Screw (V- 
684) that passes through the top of Vertical 
Mold Blade Cam Lever (V-525) until it 
holds the Vertical Mold Blade Lever (V- 
512) firmly in position; then turn the 
machine by hand and adjust the pressure 
of the Vertical Mold Blade Adjusting 
Screw so the Vertical Mold Blade, in its 
up and down motion, will be seated snugly 
against the end of the Mold without too 
much pressure but tight enough to prevent 
metal from being forced between them. 

Adjusting Vertical Mold Blade 

For Machine part numbers see plates 1, 
2, 3 and 4; Mold part numbers, plates 6 

and 7. 

It is absolutely essential that the Vertical 
Mold Blade is positioned correctly in re- 
lation to the inner left hand side of the 
Matrix Carrier, against which the Linotype 
or Intertype Matrix rests when in its cast- 
ing position, so the character will be cast 
in correct setwise position on the type. 
This adjustment, as already explained un- 
der the caption "TO REMOVE THE 
TYPE MOLD," is made at the factory, but 
if for any reason it was changed by moving 
the Mold Locating Screw (M-981) it will 
be necessary to correct it. To do this pro- 
ceed as follows: 

Remove the Type Mold, have the Lino- 
type Vertical Mold Blade (V-612) in its 
place in the Mold Stand with the Vertical 
Mold Blade Lifting Block (V-615) in the 
recessed portion thereof; turn the Hand 
Wheel (S-541) until the Vertical Mold 
Blade (V-612) is in its highest position. 
Insert a 48 point quad matrix of 12 point 
set in the Matrix Carrier (A-8) and hold 
it in position firmly against the Matrix 
Carrier Wall by locking it in place with the 
Linotype Matrix Block (G-721). Put Ma- 
trix Carrier in place on the machine and 
push it forward by hand until the Matrix 
Carrier almost touches the Vertical Mold 
Blade (V-612). Now bring the Vertical 
Mold Blade against the side of the Quad 
Matrix by turning the Vertical Mold Blade 



THOMPSON TYPE MACHINE COMPANY 



15 



Adjusting Screw (V-646) until the Vertical 
Mold Blade (V-612) rests against the Quad 
Matrix. It must touch the 48 point Quad 
Matrix evenly at both ends to make sure 
the Vertical Mold Blade is exactly square 
with the mold surface of the Mold Stand 
so as to insure even contact with the end 
of the Type Mold (A-13). 

Remove the Matrix Carrier and place the 
Mold (A-13) in the Mold Stand, being sure 
that all parts are perfectly clean, and 
tighten Mold Stand Cap Screws sufficiently 
to slightly hold the Mold. Now tighten the 
Mold Locating Screw (M-983) until it 
brings the Mold (A-13) against the Ver- 
tical Mold Blade (V-612), then tighten the 
Mold Stand Cap Screws (N-872) down 
tight. 

IMPORTANT: It is necessary now to 
adjust the Vertical Mold Blade Supporting 
Plug Set Screw (V-984), (this screw is 
located under the right hand arched portion 
of the Mold Stand [N-502 and N-503]), pro- 
ceeding as follows : Loosen the hexagon nut 
that locks the screw in position "and loosen 
the screw enough to be sure its end is not 
in contact with the brass Vertical Mold 
Blade Supporting Plug (V-960). Now 
tighten the screw slowly with the fingers, 
(use no wrench while doing this), until the 
screw gently presses the Vertical Mold 
Blade Supporting Plug (V-960) against the 
lower right hand side of the Vertical Mold 
Blade; be very careful not to force the 
Brass Plug too tight against the Vertical 
Mold Blade as that will push it too far to 
the left and force it away from the lower 
half of the Mold, thereby casting a fin on 
the type and allowing metal to collect be- 
tween the Vertical Mold Blade and the 
Mold. If the screw is too loose it will al- 
low the lower end of the Vertical Mold 
Blade to shift too far to the right and throw 
the upper end out of contact with the upper 
half of the Mold and cause the casting of 
a fin on the type. 

When you are sure the pressure of the 
Vertical Mold Blade Supporting Plug Screw 
(V-984) is exactly right, tighten the hexa- 
gon nut to lock it in position. Insert the 
Pin Wrench in one of the holes in the head 



of the screw and hold it to prevent it from 
moving while tightening the lock nut. 

If all adjustments are correctly made the 
Vertical Mold Blade will lay flat against 
the end of the Mold and the type bodies 
cast will be sharp and without any burr or 
fin on the Vertical Mold Blade side. 

When it is desired to cast type from either 
the wide or narrow Thompson matrices, re- 
move the Linotype Vertical Mold Blade 
(V-612) and replace it with the Vertical 
Mold Blade (V-613) for Thompson Mat- 
rices. 

Vertical Adjustment of the Vertical 
Mold Blade 

There is an adjustment for the Vertical 
Mold Blade (V-612 or V-613) to regulate 
its up-and-down stroke. If the type in eject- 
ing strikes the upper end of the Vertical 
Mold Blade it will be bruised and the end 
of the Mold Body (M-894) will be damaged, 
or the Mold Body Lever (M-520) may be 
broken. Therefore care must be taken that 
the Vertical Mold Blade (V-612 or V-613) 
is adjusted so its upper end is about the 
thickness of a sheet of paper below the 
lower edge of the Mold Body (M-894). If 
the Vertical Mold Blade is set too low the 
type will strike the edge of the Type Re- 
ceiving Plate (R-630). 

When it is necessary to adjust the up- 
and-down stroke of the Vertical Mold 
Blade, swing back the Metal Pot, remove 
the Matrix Carrier, and turn the machine 
by hand until the Vertical Mold Blade is 
in its highest position. Now loosen the 
Clamping Screw (X- 104-1) in the bottom 
lug of the Vertical Mold Blade Cam Lever 
(V-525); then with the Pin Wrench (E- 
981), lower the Lower Adjusting Screw 
(V-685) just a trifle; next loosen the Lock- 
nut (X-102-3) on the Upper Adjusting 
Screw (V-684) and tighten this Adjusting 
Screw until it brings the lug on the side 
of the Vertical Mold Blade Lever (V-S12) 
firmly down against the upper end of the 
Lower Adjusting Screw (V-68S) so there 
will be no lost motion of the lug on the 
Vertical Mold Blade Lever (V-512) be- 
tween the Upper and Lower Adjusting 
Screws in the Vertical Mold Blade Cam 



16 



THOMPSON TYPE MACHINE COMPANY 



Lever (V-525). Then tighten the Locknut 
(X- 102-3) on the Upper Adjusting Screw 
(V-684) and the Clamping Screw (X-104-1) 
in the lug of the Vertical Mold Blade Cam 
Lever (V-525). 

Turn the machine over by hand to move 
the Vertical Mold Blade up and down sev- 
eral times. Then bring it down to its low- 
est position and examine it to make sure 
it is now not too high or too low. If not 
exactly right make the adjustment again 
until it is correct. 

The foregoing Vertical Mold Blade ad- 
justments are for all Thompson Type- 
casters up to and including machine num- 
ber 1298. Beginning with machine number 
1299, all are equipped with a hexagon head 
screw in the machine Base Top. The head 
of this Screw (V-687) is directly under the 
Lower end of the Vertical Mold Blade and 
is adjusted at the factory. 

If it should become necessary to ad- 
just this Vertical Mold Blade Stop Screw 
(V-687), loosen the hexagon Locknut under 
its head and turn the Stop Screw (V-687) 
to the left to bring it up, or to the right to 
bring it down, and tighten the Locknut. 
Then make the other adjustments necessary 
on the Vertical Mold Blade Lever Screws 
(V-684 and V-685) as explained in the fore- 
going paragraphs. The lower end of the 
Vertical Mold Blade must rest firmly on 
the top of the Stop Screw while the type 
is being discharged from the Mold into the 
Receiving Shoe. 

The 72 Point Body Gauge 

To gauge the body size of the type you 
are casting place a sufficient number of 
pieces of type, with nicks on the side, in 
the 72 Point Gauge (A-15), plate 6, so as 
to fill it snugly. For example, if casting 6 
point type it will require 12 pieces of type 
to fill the gauge; if casting 12 point type it 
will require 6 pieces of type to fill the 
gauge; if casting 24 point type it will re- 
quire 3 pieces of type to fill the gauge. This 
type when placed in the gauge must fit 
snugly, not too tight or too loose. 

If the type is too large the fault un- 
doubtedly is due to some foreign substance 
having become lodged between the Mold 
Body Piece and the Mold Top Block 



(A-ll), or between the Mold Body Piece 
and the Mold Bottom Block (A-9). Re- 
move Body Piece and wipe thoroughly 
clean of any dirt or metal; then wipe the 
Mold Top Block (A-ll) and the Mold Bot- 
tom Block (A-9) free from all dirt and 
metal. After the Mold Body Piece and the 
Mold Body Top and Bottom Blocks have 
been wiped clean insert Body Piece in Mold 
and clamp Mold Body Top and Bottom 
Blocks in position sufficiently tight so that 
the Mold Body Piece moves freely. If all 
parts are clean the type will be perfect in 
size. 

When the type fits loose in the 72 Point 
Gauge (A-15) it is undoubtedly due to the 
Mold having become chilled by reason of 
too great a flow of water. In this case re- 
duce the flow of water slightly. After 
operating the machine a few minutes the 
type will assume the proper body size. 

Aligning Gauge 

The Aligning Gauge is to be used for 
accurately reading the alignment of type. 
Place the type you wish to test for align- 
ment on the Gauge, with the nick up, along- 
side the Lining Standard (L-989), plate 6, 
for the same size body as the type, hold 
the Aligning Gauge (A- 16), plate 6, with 
the left hand, and with the thumb press 
both the type and the Lining Standard 
against the movable blade. 

With the fingers of the right hand turn 
the screw until the sharp edge of the blade 
is in line with the edge of the face of the 
type and the edge of the Lining Standard 
(L-989). The Aligning Gauge (A-16) must 
be held so the light will fall directly on 
the edge of the blade, or it cannot be read 
accurately. 

If the line of the type you are casting 
does not accurately agree with the Lining 
Standard (L-989) correct the alignment as 
explained under the caption "MAKING 
THE ALIGNMENT". Each character 
should be tested for alignment every time 
a matrix has been changed. 

Making the Alignment When the Face to 
Be Cast Is on Standard Line 

Put the capital "H" matrix of the face 
and body you are about to cast into the 



THOMPSON TYPE MACHINE COMPANY 



17 



Matrix Carrier and place the Carrier into 
position on the machine. Do not connect 
it to the Matrix Carrier Lever, as it is de- 
sirable to move it toward and from the 
mold by hand so that you may see whether 
the aligning position of the matrix is, ap- 
proximately correct. The Lower end of the 
face when the Matrix is in position on the 
machine should be about even with the 
upper surface of the Mold Bottom Block 
Shoe, which forms the lower side of the 
Mold Casting Chamber. If necessary, turn 
the Graduated Knob on top of Matrix Car- 
rier (A-8) to bring the bottom edge of the 
Matrix Face on a line with the bottom side 
of the Mold Cavity. Now connect the Ma- 
trix Carrier to the Lever and cast one or 
two type by turning the machine over by 
hand. Place the type on the Aligning 
Gauge with the Lining Standard to test it 
for alignment. If the line is high or low, 
bring the Matrix up or down by turning 
the Graduated Knob on the Carrier to bring 
the Matrix in proper position. When the 
Alignment is correct, tighten the Slotted 
Nut in the center of the Graduated Knob 
to prevent it from turning and consequent 
changing of the line. 

When the Face to Be Cast Is Not on Stand- 
ard Line and No Type Are Available 

Align the top of the capital "T" as high 
on the body as it will go without being 
trimmed. Then align the capital "H" with 
the bottom of the "T". Now cast the lower- 
case "m" in alignment with the bottom of 
the capital "H". Then lower-case "o" to 
align with "m'\ As the round letters are 
always larger than the others allow the bot- 
tom of the "o" to extend a little below the 
"m" and then turn both letters over on the 
Aligning Gauge and it should be found that 
the "o" is a trifle higher than the top of the 
"m". Now align all round-bottom char- 
acters with the "o" and all square-bottom 
characters with the "m". Cast the lower- 
case "x" to align with the bottom of the 
"m" and align the lower-case "v", "w" and 
"y" with the top of the "is". Align such 
characters as the "g", "p" and "q" with the 
top of the "o". Proceed with the capitals 
the same way, using the capital "H" and 
"O" as guides. 



If the type is to be cast to match Lino- 
type or Intertype alignment a short slug 
of lower-case "m's" and "o-s" can be cast 
and this used as a standard. 

When once you have cast a face that is 
not on standard line save a few type of 
each the capital "H" and lower-case "m" 
for standards to which to align that face 
and size in future. These standard type 
may be saved for future use by putting 
them in a small envelope, properly labeled. 

Accurate alignment cannot be made from 
old worn type because the sharp edges of 
the face have become rounded. 

Setwise Size of Type 

Furnished with the machine are nine 
brass Set Adjusting Blocks (M-608), plate 
6, marked 1, 1%, *& 2, 3, 4, 6, 8, 10 and 
three steel Adjusting Blocks marked 20, L 
and C, respectively. Use the L Block for 
Linotype and Intertype matrices, and the 
C Block for narrow Thompson Matrices. 
Use only the numbered Blocks when cast- 
ing from wide Thompson Matrices. 

The Thompson style matrices have trie 
body size and series number stamped on 
the lower end of the matrix; the figures 
stamped near the upper end, either on the 
front or the back, designate the setwise size 
of the character. 

When casting from wide Thompson Mat- 
rices, first put the wide Matrix Holder 
(G-928), plate 7, into the Matrix Carrier 
(A-8) and slip the Matrix into the Holder 
(G-928) with the beveled corners toward 
the bottom, selecting preferably the widest 
characters first. 

Now select the number of Set Adjusting 
Blocks (M-608) necessary to make up the 
number of points indicated on the Matrix 
and insert them between the lug of the Set 
Adjusting Liner (M-905) and the Mold 
Body-Plate (M-942), plate 6, being sure 
that the sides of the Set Adjusting Blocks 
are absolutely clean to insure correct set- 
wise dimension of the type. The Set Ad- 
justing Liner Screw (M-934) must then be 
tightened to hold the Set Blocks together. 
Then put the Matrix Carrier on the ma- 
chine and raise the Matrix Carrier Fork 
(G-66S) to connect the Matrix Carrier to 
the Matrix Carrier Lever (G-924).

THOMPSON TYPE MACHINE COMPANY 



Loosen the Mold Body-Plate Outside 
Lockmit (M-707) and the Mold Body-Plate 
Inside Locknut (M-673), the Mold Body- 
Plate Adjusting Nut (M-708) must -then 
be loosened at least one-half of an inch. 
Now draw the Mold Body-Plate Adjusting 
Screw (M-674) outward as far as it will go 
and tighten the Body-Plate Inside Locknut 
(M-673). This is done to be certain that 
the Matrix Holder (G-928) will not foul 
the end of the Set Adjusting Liner (M-905) 
when the machine is turned to casting 
position. Be sure the Pump Stop (P-682) 
is in its inward position so no metal can 
pass into the Mold; turn the Hand Wheel 
(S-S41) until the Matrix rests snugly in 
its casting position against the Mold. To 
make sure of this see that the Cam Lever 
Roller (C-966) is in contact with the 
Choker Cam (C-413) or (C-519). 

Now loosen the Mold Body Plate Inside 
Locknut (M-673) and the Body Plate Out- 
side Locknut (M-707) until it reaches the 
extreme outside end of the Body Plate Ad- 
justing Screw (M-674). Then, with the 
hand, press against the Outside Locknut 
(M-707) until the end of the Set Adjusting 
Liner (M-905) contacts with the Matrix 
Holder (G-928), then first tighten, by hand; 
the Mold Body Plate Adjusting Nut (M- 
708) to bring the Set Adjusting Liner 
(M-905) firmly against the Matrix Holder 
(G-928). Now tighten the Inside Locknut 
(M-673) and finally lock it tight with the 
Outside Locknut (M-707) firmly against 
the Inside Locknut (M-673). It is advis- 
able to always make the first cast by turn- 
ing the machine by hand. 

When casting from narrow Thompson 
Matrices remove the wide Matrix Holder 
(G-928) and insert in its place the Thomp- 
son Narrow Matrix Holder (G-929). Add 
the steel Set Adjusting Block (M-608) 
marked "C" to the number of brass Set 
Adjusting Blocks in order to obtain the 
setwise size of points stamped on the Ma- 
trix. Follow the same set adjusting instruc- 
tions in this case as in casting from Wide 
Thompson Matrices. 

Linotype and Intertype Matrices 

When casting from Linotype or Inter- 
type Matrices, remove the Thompson Ma- 



trix Holder and insert the Linotype or In- 
tertype Matrix in the Matrix Carrier (A-8). 
Press the Matrix firmly against the side 
wall of the Matrix Carrier with its com- 
bination upward against the overhanging 
Top Shoe. Place an 8 point Linotype or 
Intertype blank Quad Matrix against the 
side of the letter Matrix. This forms a 
side wall for the face and prevents fins. 
Then place the Linotype Matrix Holder 
(G-721), plate 7, in the. Matrix Carrier 
(A-8) and press it firmly against the blank 
Quad Matrix and the letter Matrix while 
tightening the Screw (X- 108-11) which 
tightens the Linotype Matrix Holder 
Clamp (G-723). 

; Use only the steel Set Adjusting Block 
(M-608) marked "L", placing it between 
the lug on the Set Adjusting Liner (M-905) 
and the Mold Body Plate (M-942) and fol- 
low the Set Adjusting instructions as ex- 
plained for Thompson wide and narrow 
Matrices. 

When casting type larger than thirty 
point body from Linotype or Intertype 
matrices it is necessary to cut away about 
half of the lug on the face side of the com- 
bination end of the matrix, allowing enough 
of it to remain to form a bearing where it 
fits behind the overhanging portion of the 
Matrix Carrier Adjusting Block Top Shoe 
(919). The entire lug on the face side of 
the other end of the matrix must be cut 
away so the face of the matrix will go 
firmly against the face of the mold without 
the lugs fouling with the overhanging por- 
tions of the Mold Top and Bottom Blocks; 

In casting from Thompson wide or nar- 
row Matrices the Vertical Mold Blade 
(V-613) must be used. For Linotype or 
Intertype Matrices, use the Vertical Mold 
Blade (V-612). 

Logotypes 

Logotype can be produced from Linotype 
or Intertype Matrices by arranging the 
necessary matrices, for the word required, 
side by side in the Matrix Carrier (A-8), 
plate 7, then placing the 8 point blank Quad 
Matrix against the outer, or last, letter Ma- 
trix in the line and holding them all in 
position by clamping the Linotype Matrix 
Holder very firmly against them. To make

the "set" proceed in the same manner as for 
single type, but of course, the casting speed 
must be slower. 

Making the Setwise Size of Type With the 
Micrometer Set Adjusting Device 

NOTE: The new Matrix Holder Style "B," plate 8, for 
both wide and narrow Thompson, Matrices must be used with 
the Micrometer Set Adjusting Device. 

The Thompson style matrices have the 
body size and series number stamped on 
the lower end of the matrix ; the figures 
stamped near the upper end, either on the 
front or the back, designate the setwise 
size of the character. 

The Micrometer Set Adjusting Device, 
plate 8, is just to the right of the mold as 
you face the machine, being easily distin- 
guished as it is the only part of the mold 
stand not enameled. The top surface of 
this device has thirteen graduations from 
to 48 inclusive, each line representing 4 
points. Setwise sizes are made by a screw 
adjustment, or Measuring Screw (203), on 
which is a collar with 32 graduations, each 
division measuring Y% point. The Collar is 
marked 0, 1, 2, 3; indicating 1, 2, etc., points. 
This collar is set before the machine leaves 
the factory so that when the zero mark is 
in line with the indicator and also the indi- 
cator on the Set Device Stop Nut (202) 
aligns with the zero mark on the top of the 
Set Device Body (201) the end of the Mold 
Body (M-894) in the mold is against the 
Vertical Mold Blade (V-613). Do not 
change this adjustment. 

Before inserting the matrix into, the 
holder ascertain the setwise size on which 
the particular character is to be cast as ex- 
plained in the first paragraph above. Then, 
to make set, loosen the Mold Body Plate 
Outside .Locknut (M-707), Mold Body 
Plate inside Locknut (M-673), both of 
which are on the Mold Body Plate Ad- 
justing Screw (M-674) between the Mold 
Body. Lever (M-520) and the Mold (A-13), 
then loosen the Mold Body Plate Adjusting 
Nut (M-708), which is to the right of the 
Mold Body Leven Be sure the Pump Stop 
(P-682) is in its inward position so no 
metal can pass through the nozzle into the 
mold. Turn Hand Wheel until upper end 
of the Mold Body Lever (M-520) is at its 



farthest position to the right; to make sure 
of this see that the Cam Lever Roller 
(C-966) is in contact with the Choker Cam 
(0413). 

Loosen Clamping Screw (207) in front 
of Set Device Body (201) and turn Measur- 
ing Screw (203) to the left, or to the right, 
until the indicator on the Set Device Stop 
Nut (202) aligns with the graduation on 
the Set Device Body (201) nearest to the 
set indicated on the matrix. If the reading 
is not exact use the graduation on the Set 
Device Measuring Screw Graduated Collar 
(204) to bring the set to the correct dimen- 
sion. For example, if the set indicated on 
the matrix is 17j4, in turning the Measur- 
ing Screw (203) stop at "16" on the Set 
Device Body (201), then turn to the second 
graduation past the figure "1" on the Grad- 
uated Collar (204), which will give the 17 }i 
setwise size required. 

Tighten Clamping Screw (207) firmly 
with pin wrench. Turn the Mold Body 
Plate Adjusting Nut (M-708) to the right 
until the stop on the Mold Body Plate 
(M-942) is brought back firmly against the 
stop on the Set Device Stop Nut (202). 
After this is done tighten the Mold Body 
Plate Inside Locknut (M-673) and Mold 
Body Plate Outside Locknut (M-707). 

Now insert the Matrix in the Matrix 
Holder with the beveled corners on the ma- 
trix toward the bottom. It is preferable to 
begin casting from the thinnest characters 
first. After making the matrix secure in 
the holder by tightening with the knurled 
head screw put the Matrix Carrier (A-8) 
on the machine and raise the Matrix Car- 
rier Fork (G-665) to connect the Matrix 
Carrier to the Matrix Carrier Lever (G- 
924)* It is advisable to always make the 
first, cast by turning the machine by hand. 
; When casting from Linotype or Inter- 
type Matrices remove the Thompson Ma- 
trix Holder by turning the knurled knob 
on the Matrix Carrier to the left until the 
Matrix Holder is freed from the adjusting 
screw. Replace the Thompson Matrix 
Holder with the Standard Matrix Carrier 
Adjusting Block, plate 8, by reversing the 
operation of removing the Matrix 'Holder. 
Insert the ILinotype or Intertype Matrix in 



20 



THOMPSON TYPE MACHINE COMPANY 



the Matrix Carrier (A-8), press the Matrix 
firmly against the side wall of the Matrix 
Carrier with its combination upward 
against the overhanging Top Shoe. Place 
an 8 point Linotype or Intertype Blank 
Quad Matrix against the side of the letter 
Matrix. This forms a side wall for the face 
and prevents fins. Then place the Linotype 
Matrix Holder (C-721) in the Matrix Car- 
rier (A-8) and press it firmly against the 
blank Quad Matrix and the letter Matrix 
while tightening the Screw (X-108-11) 
which tightens the Linotype Matrix Clamp 
(C-723). Now gently tighten the small 
screw which passes through the Linotype 
Matrix Clamp so its end bears against the 
blank Quad Matrix to prevent the casting 
of any fin between the Linotype Letter Ma- 
trix and the Quad Matrix. 

As the thickness of a Linotype or Inter- 
type Matrix is of the proper setwise size 
of the character proceed in this manner to 
obtain the proper set for the character be- 
ing cast. Loosen the Mold Body Plate Out- 
side Locknut (M-707), Mold Body Plate 
Inside Locknut (M-673) and Moid Body 
Plate Adjusting Nut (M-708). Push, with 
hand, the Mold Body Plate Adjusting 
Screw (M-674) until the end of the Mold 
Body (M-894) is against the Vertical Mold 
Blade (V-612). Place the Linotype or In- 
tertype Matrix against the stop on the 
Mold Body Plate (M-942), and after loosen- 
ing Set Device Clamping Screw (207) turn 
Set Device Measuring Screw (203) until 
the stop on the Set Device Stop Nut (202) 
is firmly against the matrix. Now remove 
the matrix and proceed exactly as in para- 
graph under this caption. 

In casting from Thompson wide or nar- 
row Matrices the Vertical Mold Blade 
(V-613) must be used. For Linotype or 
Intertype Matrices use the Vertical Mold 
Blade (V-612). 

To Adjust the Type Receiving Shoe 

When one size body is changed for an- 
other size the Type Receiving Shoe (A-14) 
must be adjusted so the size type to be cast 
will fit under it without being either too 
tight or too loose. 

First remove the Type Receiving Shoe 



(A-14), plate 2, then turn the Hand Wheel 
(S-541) over by hand until the end of the 
Mold Body (M-894) is at the extreme end 
of its stroke outside of the left hand end of 
the Mold (A-13), plate 7. Now place a type, 
with its nick up, of the same size as the 
Body in the Mold, on top of the lower Type 
Receiving Plate (R-630), plate 2, at its ex- 
treme left end ; then put the Type Receiv- 
ing Shoe (A-14) back on the Mold Stand 
(N-S02), the right end of the Receiving 
Shoe (A-14) will then rest on the project- 
ing end of the Body Piece and the left end 
will rest on the type. Now tighten the 
Type Receiving Shoe Adjusting Screws 
(R-696) using the Pin Wrench (E-981), 
plate 20, to fasten the Screws (R-696) 
firmly. If the Type Receiving Shoe (A-14) 
is not down in proper position the Foot 
Plow (T-974) and the Type Trimming 
Knives (T-726 and T-727) will not properly 
trim the type. The Type Stripper Spring 
(R-679) will also fail to strip the type from 
the Body and hold it. If pressed down too 
tightly the end of the Mold Body (M-894) 
may be damaged, or the Type Receiving 
Shoe (A-14) or the Type Receiving Plate 
(R-630) may be cut by the end of the 
Mold Body. In casting the larger sizes of 
type, from 14 point to 48 point, it is good 
practice to put a piece of thin paper on top 
of the Mold Body (M-894) when setting 
the Type Receiving Shoe (A-14) to prevent 
damage to those parts. This thin paper 
passes through the Receiving Shoes with 
the type as they are cast. 

Connecting and Adjusting Metal Pot 

The Metal in the Pot Crucible (H-571), 
plate 2, must be thoroughly melted before 
it is locked into casting position against 
the Mold; if it is locked up while the sur- 
face metal or metal in the Nozzle (H-57S) 
is not fully melted it will cause leakage at 
the Nozzle hole. When lighting the Burn- 
er under the Pot to melt the metal the Pot 
must be back away from the mold. While 
it is in this position, just before locking it 
against the Mold, the Choker should be 
moved back and forth to make sure it does 
not stick in the Nozzle (H-575) or Choker 
Channel (C-580). To move the Choker 



THOMPSON TYPE MACHINE COMPANY 



21 



back and forth use the Choker Tripping 
Tool (C-837) and hook it over the Choker 
Lever (C-854) at the point above the 
Choker Lever Link (C-527). Press down 
on the end of the Choker Tripping Tool 
(C-837) until the metal flows freely out of 
the hole in the Nozzle (H-575) ; move the 
end of the Tripping Tool quickly up and 
down a few times to move the Choker back 
and forth. The Jet Box (J-597) or the 
Ladle (X-128-2) should be held before the 
Nozzle to catch the molten metal as it 
flows out. 

Wipe the Nozzle (H-S75) and the Nozzle 
Plate (H-639) absolutely clean; also see 
that no dirt or metal lies between the Noz- 
zle Plate (H-639) and the Mold (A-13). 
Turn the Pot Yoke Lock Handle (H-763) 
far enough so the flat surface of the toe of 
the Pot Yoke (H-506) will pass under the 
flat side of the Pot Yoke Lock (H-692) ; 
then swing the Metal Pot around toward 
the Mold, at the same time holding up the 
Pump Lever (P-537) so the opening in the 
lower end of the Pump Lever Link (P-526) 
will engage the end of the Pump Cam 
Lever (P-S24). Now turn the Pot Yoke 
Handle (H-763) in the proper direction to 
lock the Pot against the Mold. 

If the Pot Yoke Lock Handle (H-763), 
plate 2, does not turn freely examine the 
Nozzle (H-575) for escaping metal; also 
see that there is no dirt or metal on the toe 
of the Pot Yoke (H-506) where the Pot 
Yoke Lock (H-692) engages it, as this may 
prevent the Metal Pot from coming for- 
ward into locking position. 

There is a Rear Pot Adjusting Screw 
(X-l 14-11) that passes through the Pump 
Lever Support (P-548) against the rear lug 
of the Pot (H-571). This should be only 
tight enough to hold the Pot against the 
Mold and prevent leakage of metal between 
the Nozzle (H-575) and the Nozzle Plate 
(H-639) while casting type. It is very im- 
portant that this pressure is not excessive, 
as that would cause the Vertical Mold 
Blade (V-613) or the Jet Ejector (J-893) to 
stick as they move along the face of the 
Nozzle Plate (H-639). It is also very im- 
portant that the Metal Pot (H-571) sets 



square with the back of the Mold (A-13) to 
prevent squirts. 

When the Pot (H-571) requires adjust- 
ing proceed as follows: First lock the Pot 
into casting position, being sure that the 
Pump Stop (P-682) is in position under the 
Pump Cam Lever (P-524) to prevent leak- 
age of metal through the Nozzle while the 
adjustment is being made. Then loosen the 
hexagon head Pot Screws (X-120-3) that 
pass through the side lugs of the Pot into 
the Pot Yoke (H-506) ; also loosen the Rear 
Pot Adjusting Screw (X-l 14-11) by first 
loosening the hexagon lock nut thereon and 
then turning the Adjusting Screw (X-l 14- 
11) to the left. 

Now turn the Pot Adjusting Screw (X- 
114-11) to the right enough only to move 
the Pot (H-571) forward until it presses 
against the Mold (A-13) without binding 
the Nozzle Plate (H-639) too tightly be- 
tween the Nozzle (H-575) and the Mold 
(A-13). Now tighten the hexagon head 
Pot Screws (X-120-3) down firmly to hold 
the Pot in position on the Pot Yoke (H- 

506). 

After the pot pressure adjustment has 
been made, take hold of the wire Nozzle 
Plate Handle (H-768) and move the Nozzle 
Plate (H-639) with a rocking motion be- 
tween the Nozzle (H-575) and the Mold 
(A-13) while the Pot is locked in its cast- 
ing position to ascertain whether the pres- 
sure of the Pot against the Mold is correct. 

Sidewise Adjustment of Metal Pot 

When it is necessary to adjust the Metal 
Pot, either to the right or to the left, in 
order to bring the hole in the Nozzle (H- 
575) and the Nozzle Plate (H-639) directly 
in front of the Jet opening in the Mold pro- 
ceed as follows: First lock the Pot into 
casting position, being sure that the Pump 
Stop (P-682) is in position under the Pump 
Cam Lever (P-524) to prevent leakage of 
metal through the Nozzle (H-575) while 
the adjustment is being made. Loosen the 
hexagon head Pot Screws (X-120-3), plate 
2, that hold the Pot on the Pot Yoke (H- 
506) ; also loosen the Rear Pot Adjusting 
Screw (X-l 14-1.1), plate 2, and the hexagon 
head Choker Lever Adjusting Screw (X- 



22 



THOMPSON TYPE MACHINE COMPANY 



120-1) which holds the Choker Lever (C- 
534) in place. 

Now move the Pot (H-S71) to the right, 
or to the left, by first loosening the large 
head Pot Adjusting Screw (H-415), plate 
2, -on that side of the Pot to which it is to 
be shifted and then tighten the Pot Ad- 
justing Screw (H-415) on the other side 
until the Pot is moved over as far as re- 
quired. Be sure to tighten all the screws 
that hold the Pot sidewise, forward and 
down, and the Choker Lever Screw (C-534) 
that holds the Choker Lever in place be- 
fore attempting to cast type. 

NOTE: When the machine is an old model, without Pot 
Adjusting Screws (H-415), it will be necessary to drive the 
Metal Pot (H-571) to the right, or to the left, with a 
hammer when making the sidewise adjustment. 

Quick Change Holder for Foundry Style 

Matrices 

Foundry Style Matrices can be as easily 
and quickly adjusted in the Quick Change 
Holder as Thompson Matrices in the Stand- 
ard Holder. This is an important feature. 

To insert a matrix in the Quick Change 
Holder, plate 9, loosen the Clamping Screw 
(219), place the matrix between the jaws 
of the Holder and tighten the Clamping 
Screw (219). This brings the Top Jaw 
(217) down to the end of the matrix and 
the Latch (218) against the back of the 
matrix at the same time, thereby locking 
it firmly in the Holder. Use the fingers 
only to tighten the Clamping Screw ; to use 
pliers may result in damage to the Holder. 

To adjust the Mold Body for setwise size 
of the character, when using Foundry Style 
matrices in that style of Holder which has 
no Side Plate for contact with the end of 
the Set Adjusting Liner (M-905), it is 
necessary to first select the Set Adjusting 
Blocks (M-608) to equal the side bearing 
of the matrix; this is the distance between 
the character and the side of the matrix 
nearest the Set Adjusting Liner; this varies 
in different sizes and in different plants, 
sometimes it is less than 5 points and some- 
times 8 points or more; add to them the 
necessary Set Adjusting Blocks that equal 
the width of the character to be cast and 
insert. all of them between the lug of the 
Set Adjusting Liner (M-905) and the Mold 



Body Plate (M-942). Then make the set- 
wise size adjustment of the Mold Body in 
the same manner as explained in a preced- 
ing article under the caption "SETWISE 
SIZE OF TYPE". 

When the Quick Change Holder has a 
Side Plate for contact with the end of the 
Set Adjusting Liner no Set Adjusting 
Blocks to equal the side bearing of the ma- 
trix are required. Select only the Set Ad- 
justing Blocks required to equal the width 
of the character to be cast and make the 
setwise adjustment as explained in the fore- 
going paragraph. 

If the machine is equipped with the mi- 
crometer Set Adjusting Device, plate 8, 
make the setwise adjustment as explained 
under the caption "MAKING THE SET- 
WISE SIZE OF TYPE WITH THE 
MICROMETER SET ADJUSTING DE- 
VICE". 

Special Matrix Carrier With Adjustable 

: Side Wall 

The Special Adjustable Matrix Carrier, 
plate 9, is necessary to cast Vernacular 
Type from foundry style matrices as it en- 
ables the operator to cast the character in 
any desired position on the end of the 
body; it can also be used for Thompson, 
Linotype and Intertype matrices by the 
purchase of the necessary holders. 

To change the position of the character 
on the end of the body, first place the foun- 
dry style matrix in the Quick Change Hold- 
er and tighten the Clamping Screw (219) 
only slightly so the matrix can be shifted 
sideways if necessary. Then release the 
small clamping screw that passes through 
the left side wall of the Matrix Carrier into 
the Adjusting Wedge (212). Next turn the 
Wedge Adjusting Screw (213) in the neces- 
sary direction to move the Adjusting 
Wedge (212) to the right, or to the left, in 
order to bring the matrix in the desired 
position in front of the mold, so the char- 
acter will be cast in the desired sidewise 
position on the end of the type. Tighten 
the small clamping screw to hold the Ad- 
justing Wedge firmly against the Matrix 
Carrier Side Wall ; loosen the Matrix Car- 
rier Clamping Screw (219), push the Ma- 



THOMPSON TYPE MACHINE COMPANY 



23 



trix firmly against the Matrix Carrier Ad- 
justing Wedge (212) and then tighten the 
Matrix Holder Clamping Screw (219) to 
hold the matrix firmly in position. 

Place the Matrix Carrier in the machine 
and adjust the Mold Body for the setwise 
size desired, as described in a preceding 
paragraph under the caption, "QUICK 
CHANGE HOLDER FOR FOUNDRY 
STYLE MATRICES". 

- If the machine is equipped with the New 
Set Adjusting Device make the setwise ad- 
justment as explained under the caption, 
"MAKING THE SETWISE SIZE OF 
TYPE WITH THE MICROMETER SET 
ADJUSTING DEVICE". 

Now cast one or two type and if the set- 
wise size is found to be correct, and the 
character in the desired position, proceed 
with casting/ But if the character is not in 
the desired sidewise position on the end of 
the body remove the Matrix Carrier, move 
. the matrix to the right, or to the left, in the 
Holder to bring the character into the cor- 
rect position by making the necessary ad- 
justments as explained in the second para- 
graph under, this caption. 

To Replace Foundry Style Matrix Holder 
With the New Style "B" Matrix Holder 

The Style ■■■""■■B" Matrix Holder, plate 8, 
is for both wide and narrow Thompson 
Matrices. It must be ^sed on machines 
with the new Micrometer Set- -"Adjusting 
Device; it cannot be used on machines 
where the Set Adjusting Blocks (M-608) 
and the Set Adjusting Liner (M-905) are 

still, in use. 

Remove the Foundry Style Matrix Hold- 
er, plate 9, by first ..releasing the nut in the 
top center of the.; Graduated Knob on: top 
of the Matrix Carrier; turn this Graduated 
Knob to the left until the Matrix. Holder 
is. disengaged from- the Adjusting Screw, 
This Will allow the Holder; to. be withdrawn 
from the Matrix Carrier,.: :: 

Now: place the Style ■ "B" Matrix Holder 
in the Carrier and screw it into position by 
turning the Graduated Knob to the right 
until the Holder is drawn wellup into the 
Carrier. Then release the small Clamping 
Screw that passes through the left side 



wall of the Matrix Carrier into the Adjust- 
ing Wedge; next turn the Adjusting Wedge 
Screw to the left in order to bring the Ad- 
justing Wedge downward until its inner 
edge rests snug against the side of the Style 
"B" Matrix Holder. Now tighten the small 
Clamping Screw to hold the Adjusting 
Wedge firmly against the Matrix Carrier 
Side Wall; this brings the Rib, which pro- 
jects beyond the forward end of the Ad- 
justing Wedge, just eight points from the 
Style "B" Matrix Holder and acts as a side 
guide for both wide and narrow Thompson 
Matrices. 

To Replace Style "B" Matrix Holder With 
Holder for Space and Quad Matrices 

Remove the Foundry Style Matrix Hold- 
er by first releasing the Nut in the top 
center of the Graduated Knob on top of the 
Matrix Carrier; next turn this Graduated 
Knob to the left until the Matrix Holder 
is disengaged from the Adjusting Screw. 
This will allow the Holder to be easily re- 
moved from the Matrix Carrier. 

Next place the Matrix Carrier Adjusting 
Block (918), plate 8, in the Carrier and 
screw it into position by turning the Grad- 
uated Knob to your right. Insert Quad Ma- 
trix in position and place Linotype Matrix 
Holder (G-721), plate 8, firmly against 
matrix to keep it in place. 

Make the necessary adjustments for cast- 
ing spaces and quads as explained under the 
caption, "QUAD AND SPACE MAT- 
RICES.""/ 

Quad and Space Matrices (Old Pattern) 

: The Quad Matrices (G-788), plate 6, are 
used with the Linotype Matrix equipment 
and the Linotype Vertical Mold Blade (V- 
612). Insert the Quad and Space Matrix in 
the Matrix Carrier (A-8) in the same man- 
ner as the Linotype Matrix. The Top num- 
ber stamped on the side of the Space or 
Quad Matrix (G-788) is the body size ; the 
Other number is the setwise size in points.. 
Consult the Quad Matrix Table to ascertain 
what combinations to employ to make any 
desired setwise size. 

Before connecting the Matrix Carrier 
(A-8) to the Matrix Carrier Fork (G-665), 
push the Matrix Carrier" by hand against 



24 



THOMPSON TYPE MACHINE COMPANY 



the Mold to see if the Quad Matrix is 
properly aligned so as to enter the Mold 
freely. If the projecting portion of the 
Quad Matrix is either too high or too low, 
they will be sheared by the Mold as they 
enter the casting chamber, Care must be 
exercised, therefore, to push the Matrix 
Carrier until the toe of the Matrix is only 
just in front of the casting chamber; then 
examine closely and if necessary bring the 
Matrix either up or down by turning the 
Graduated Knob on top of the Matrix Car- 
rier (A-8) in the proper direction so the 
Matrix toe will enter the mold chamber 
freely. 

Remove the Upper Type Receiving Shoe 
(A-14) and take off the Type Trimming 
Knife (T-727). Remove also the Lower 
Type Trimming Knife (T-726) and replace 
it with the Quad Trimming Knife (T-725). 
The Quad Trimming Knife (T-72S) will 
trim off any burr that may be cast on the 
end of the Space or Quad. The Foot Plow 
(T-974) remains in place the same as when 
casting type. 

Replace the Upper Type Receiving Shoe 
(A-14) and adjust it .the same as when cast- 
ing type. 

Put the steel Set Adjusting Block (M- 
608) marked "C" between the lug on the 
Set Adjusting Liner (M-905) and the Mold 
Body Plate (M-942) the same as when cast- 
ing type. This is done to bring the end of 
the Set Adjusting Liner (M-905) back some 
distance from the end of the Mold Body 
(M-894) so it will not touch the side of the 
Quad Matrix and give the Matrix Carrier 
(A-8) ample time to move to its furthest 
position away from the Mold before the 
Set Adjusting Liner starts to come forward 
while the Quad is being ejected from the 
mold, thereby avoiding striking the toe of 
the Quad Matrix. 

Make the setwise adjustment the same 
as for casting type. The Set Adjusting 
Liner should not bear against the Quad 
Matrix as when casting type, but the end 
of the Mold Body bears against the toe of 
the Matrix. 

Improved Equipment for Casting Spaces 

and Quads 

The improved equipment for casting 



spaces and quads can be used only on ma- 
chines with the Micrometer Set Adjusting 
Device, plate 8. It consists of low Space and 
Quad Bodies and a special Spacer to be 
used in the Type Mold (A-13), also steel 
Space and Quad Matrices, plate 8. To use 
this equipment proceed as follows : 

Remove the Mold (A-13), plate 7, as ex- 
plained under the caption, "To Remove the 
Type Mold". Then take out the two small 
fillister head screws that pass through the 
mold front wall ; this releases the Spacer 
which can now be withdrawn from the Mold. 
Replace this with the Spacer for Space and 
Quad Bodies by sliding it into the place 
against the Mold Front Wall from which 
you have just removed the Type Body 
Spacer. Fasten it firmly in position with the 
two fillister head screws. 

The Spacer for Space and Quad Bodies is 
thicker than the one for type Bodies and 
makes up the difference in height between 
the Space and the Type Bodies, so the Space 
Body and Jet Ejector will fit correctly be- 
tween the Mold Back Wall and the Spacer 
against the Mold Front Wall. 

Now slide the Mold Body Plate (M-942) 
into the Mold, put the Jet Ejector and the 
Space and Quad Body, of the desired size, 
into the mold and move them back and forth 
to make sure they are not too tight. If they 
bind it indicates there is dirt between some 
of the parts you have just assembled; all 
dirt must then be removed before the Mold 
is placed into the Moid Stand. 

Replace the Mold on the machine as in- 
structed under the caption, "To Replace the 
Mold". Either Vertical Mold Blade (V-612) 
or (V-613), plate 6, can be used in casting 
spaces and quads with this equipment. 

Only one steel Matrix, plate 8, is required 
to cast all setwise sizes of spaces and quads 
for any one body. Select the space and quad 
steel Matrix for the size Body you have in 
the Mold, place it in the style "B" Matrix 
Holder, press it firmly against the Matrix 
Carrier Side Wall and tighten the knurled 
head Clamping Screw to hold it firmly in 
place. 

Take the Matrix Carrier Fork (G-665) out 
of the Matrix Carrier Lever (G-924), as it 
must not be left on the machine while cast-

ing spaces and quads with this equipment. 
Put the Matrix Carrier in the machine, push 
it forward until the Toe of the Matrix is 
just in front of the Mold Casting Chamber, 
then examine closely and, if necessary, bring 
the Matrix either up or down by turning the 
Graduated Knob on top of the Matrix Car- 
rier in the necessary direction so the Matrix 
Toe will enter the mold chamber without 
binding on either top or bottom. 

When the Matrix is adjusted so its Toe 
will enter the mold chamber freely, press the 
Matrix Carrier forward until the matrix is 
tight against the face of the Mold ; the Toe 
of the matrix then rests against the forward 
side of the Space and Quad Body. Now lock 
the Matrix Carrier firmly in its castng posi- 
tion by first releasing the fillister head 
Clamping Screw, which passes through the 
middle of the right hand forward extension 
of the front wall of the Mold Stand (N-503) 
into the Matrix Carrier Slide (G-671) ; then 
tighten the long Slide Adjusting Screw (G- 
695), the head of which is in the right hand 
end of the front wall of the Mold Stand. 
Next tighten the short Slide Adjusting 
Screw (G-694) that passes through the for- 
ward end of the Mold Stand forward exten- 
sion; tightening these two Slide Adjusting 
Screws drives the right hand Matrix Carrier 
Slide firmly against the Matrix Carrier and 
holds it rigidly in position while casting 
Quads or Spaces. 

Now make the setwise adjustment as ex- 
plained under the caption, "Making the Set- 
wise Size of Type With the Micrometer Set 
Adjusting Device". 

Once all adjustments are made it is not 
necessary to remove the Matrix from the 
Mold when changing from the thinnest 
space to the widest quad as all setwise 
changes are made with the new Set Adjust- 
ing Device. 

Quotation Quads 

Quotation, or hollow, quads are cast in 
the same manner as types are cast by 
taking the Space and Quad Steel Matrix out 
of the Matrix Holder and replacing it with 
the special Quotation Quad brass Matrix, 
plate 8, making the setwise size in the same 
manner as described above. 



Quad Trimming Knife 

The Quad Trimming Knife (T-725) , 
plate 6, must be attached to the Type Re- 
ceiving Plate (R-630) by removing the 
Type Trimming Knife (T-726) and attach- 
ing the Quad Trimming Knife in its place. 
It trims of! any burr that may appear on 
the end of the Spaces or Quads after they 
leave the Mold. Remove also the Type 
Trimming Knife (T-727) -from the Type 
Receiving Shoe (A-14) to make room for 
the upper end of the Quad Trimming Knife 
(T-725). 

Type Trimming Knives 
There are two Type Trimming Knives, 
one is the Upper Type Trimming Knife 
(T-727), plate 6, which is located in the 
Type Receiving Shoe (A-14), the other is 
the lower Type Trimming Knife (T-726) 
and is located in the Type Receiving Plate 
(R-630), plate 6. These Knives trim the 
bodies at the face end of the type as they 
pass between their cutting edges. 

As these Trimming Knives must be kept 
sharp they must be removed from the Up- 
per Type Receiving Shoe (A-14) and the 
Lower Type Receiving Plate (R-630) 
whenever they are sharpened. They are 
easily adjusted by the Screws (X-108A-1) 
that pass through slotted holes in the Trim- 
ming Knives and should be set so the end 
of the last tooth is even or level with the 
surfaces of both the Type Receiving Shoe 
(A-14) and the Type Receiving Plate (R- 
630). 

When casting type with kerns or over- 
hangs, the Top or Bottom Trimming 
Knives may be removed to permit the over- 
hangs to pass. As these Trimming Knives 
(T-726 and T-727) are principally for 
trimming type cast from Linotype and In- 
tertype Matrices they should be set to trim 
the face without cutting deeply into the 
type body. 

Temperature of Metal 

A suitable thermometer, such as is fur- 
nished with the Thompson Typecaster, is 
essential. The temperature at which the 
metal is to be run depends on the grade of 
metal used. If old type-foundry metal is 
used the temperature should be about 725 



degrees Fahrenheit ; good type metal pur- 
chased from a first class metal maker should 
also be run at about the same temperature. 
If softer grade of metal is used the tem- 
perature should be lower. Linotype metal 
should be run at about 650 degrees when 
casting thin setwise characters. This tem- 
perature may be reduced when casting large 
type. 

A good rule is to run the metal at the low- 
est temperature possible to get good sharp 
faces and solid bodies. The operator must 
be careful not to overheat the metal, as that 
burns out the tin, separates the antimony 
from other metals of which good type metal 
is composed and, therefore, destroys its 
flowing and wearing qualities. It is. of the 
first importance, and an essential to suc- 
cessful results, to use the metal at the proper 
temperature and not to damage it by over- 
heating. A product or uneven type at once 
indicates improper handling of metal or a 
poor or unsuitable quality of metal. 

Cleaning Metal 

The metal in the melting pot of the caster 
should be cleaned once every day or two. 
Throw a piece of tallow about as large as 
a small walnut into the molten metal and 
stir thoroughly (this will wash all the 
metal out of the dross), then skim of! the 
dross. This treatment improves the metal. 

After metal has been, cast into type, leads, 
slugs and rules several times it is apt to. be- 
come brittle or soft; brittle if the tin is 
burned out, soft if tin and antimony are 
both .reduced.:. Tin should then be added 
when remelting. If tin and antimony are not 
at hand a liberal quantity of new type metal 
added to the old metal will greatly, improve 
it It. is generally possible to arrange. with 
a metal supply company to renew metal at 
a small cost per pound. 

For detailed information regarding type 
metal see article under the caption "Prac- 
tical and Metallurgical points regarding care 
and handling of metal". 

Adjusting Matrix Carrier Lever 

The Matrix Carrier (A-8), plates 7 and 8, 
is pressed resiliently against the Mold (A- 



13) by the Matrix Carrier Cam Lever Spring 
(G-926), which is located between the upper 
section Matrix Carrier Lever (G-924) and 
the lower section Matrix Carrier Cam Lever 
(G-92S). This Spring (G-926) is held in 
place by the Matrix Carrier Lever Screw 
(G-923). 

The Matrix Carrier Lever Screw (G-923), 
plate 5, must be adjusted so the pressure 
of the Matrix Carrier Cam Lever Spring 
(G-926) holds the Matrix snug against the 
face of the Mold. If the Matrix does not 
bear firmly against the Mold proceed as 
follows: Remove the Matrix Carrier/clean 
the Mold face and the Matrix, put Matrix 
Carrier back on the machine and connect it 
to the Matrix Carrier Fork (G-665) ; push 
the Pump Stop (P-682) inward to prevent 
metal from flowing into the Mold, and turn 
the Hand Wheel (S-541) in its casting 
direction until the Matrix is in its casting 
position in front of the Mold. 

Now loosen the Matrix Carrier Cam Lever 
Screw Nut (G-947'}4) on the inner end of 
the Matrix Carrier Lever Screw (G-923), 
then loosen the Matrix Carrier Lever Screw 
(G-923) gradually until the Matrix bears 
firmly against the face of the Mold. Again 
tighten the Matrix Carrier Cam Lever Screw 
Nut (G-947y 2 ) to prevent the Screw (G- 
923) from moving. 

When this adjustment is correctly made 
the Concave Washer (G-987) should have 
about 1/64" play between the head of the 
Matrix Carrier Lever Screw (G-923) and 
the Matrix Carrier Lever (G-924). This 
play is taken up by the tension of the Spring 
as the Matrix Carrier leaves the front of the 
Mold. 

The Pump Stop 

The outer end of the Pump Stop (P-682) 
is located between the Cam Lever Shaft 
(K-585) and the Machine Base Top (B-801), 
about. 2y 2 inches from the left hand end of 
the Mold Stand (N-502). When this Pump 
Stop is pushed inward toward the Metal 
Pot its inner end disengages the Choker 
Lever Link (C-527) from the Choker Cam 
Lever (C-523) and lays under the Pump 
Cam Lever (P-S24), thus preventing the 



THOMPSON TYPE MACHINE COMPANY 



27 




casting of type even though the machine 
is running. It is a safety device to prevent 
metal from passing through the Nozzle 
(H-575) when the operator is making ad- 
justments while the Metal Pot is locked in 
its casting position. 

Always press the Pump Stop (P-682) in- 
ward as far as it will go so the Pump Cam 
Lever (P-524) rests on the Pump Stop be- 
fore stopping the machine, or disconnecting 
the Metal Pot when you swing it away from 
the Mold (A- 13). When ready to cast start 
the machine at the proper speed and then 
pull out the Pump Stop. 

Pump Spring Adjustment 

It is obvious that in casting different sizes 
of type the tension on the Pump Spring 
(B-791) must be varied. The larger sizes 
of type require more tension on the Pump 
Spring (P-791) than the smaller sizes. 

To increase the tension on the Pump 
Spring (P-791) turn the crank on the Pump 
Spring Tension Ratchet (P-900), located 
outside the rear of base about six inches 
above the floor, in a clock-wise direction. 
To decrease the tension turn it in a counter 
clock-wise direction. In order to turn the 
Pump Spring Tension Ratchet (P-900) in 
a counter clock-w r ise direction, first release 
it by raising the lever end of the Pump 
Spring Tension Ratchet Pawl (P-901) high 
enough to clear the top of the ratchet teeth , 
this must not be done, however, unless you 
are holding onto the crank handle of the 
Pump Tension Ratchet (P-900). After the 
tension is correct the lever end of Tension 
Ratchet Pawl (P-901) must be lowered to 
again engage the teeth of the Pump Tension 
Ratchet. The proper spring tension is easily 
arrived at after a little experience. 

Matrix Carrier Slide Adjustments 

If the Matrix Carrier (A-8), plate 1, is not 
snug between the 'Matrix Carrier Slides 
(G-670 and G-671) in the Mold Stand (N- 
502 and N-503) it will affect the alignment 
of the type. When necessary to adjust this 
proceed as follows : 

Loosen the Fillister Head Clamping 
Screw (X-108-18), which passes through the 



right hand forward extension of the front 
wall of the Mold Stand (N-503) into the 
Matrix Carrier Slide (G-671) midway be- 
tween the short Slide Adjusting Screw (G- 
694) and the long Slide Adjusting Screw 
(G-695). Then turn the short Slide Adjust- 
ing Screw (G-694) and the long Slide Ad- 
justing Screw (G-695) to the right; this 
drives the Right Hand Matrix Carrier Slide 
(G-671) toward the Matrix Carrier (A-8). 
Turn these screws just enough to allow the 
Matrix Carrier to slide forward and back 
on the Slides freely without binding and 
without any side play. Be sure the Matrix 
Carrier is not tighter between the Slides at 
one end than the other, then tighten the 
Matrix Carrier Slide Clamping Screw (X- 
108-18), thus pulling the Slide (G-671) 
firmly against the ends of the Adjusting 
Screws (G-694 and G-695) and locking it. 

Adjusting Choker Cam and Choker Cam 

Roller 

The Choker Cam (C-413), plate 3, should 
be so adjusted that it will bring the Choker 
(C-531) against its seat in the Choker Chan- 
nel Bushing (C-580) at the same instant 
that the Pump (P-572) is ready to drop. 

To make the above adjustment proceed 
as follows : 

Unlock the Metal Pot, swing it back away 
from the Mold, release the tension of the 
Pump Spring so that it will give only a 
slight pull on the Pump Cam Lever; then 
pull forward the Pump Stop so that the 
roller on the Pump Cam will drop into the 
recessed portion of the Cam when the Cam 
Shaft is rotating in the clock-wise or cast- 
ing direction. 

Now turn the Cam Shaft very slowly by 
hand until the Pump Cam Lever Roller 
drops into the recessed part of the Pump 
Cam. Then pull the hand wheel backward 
toward you so that the end of the Pump 
Cam Lever abuts against the recessed por- 
tion of the Cam. In other words, pull the 
hand wheel backward until the Cam is 
brought to an abrupt stop by the lever. The 
machine is then in position for making the 
Choker Cam Adjustment. 

Loosen the hexagon head cap screw 



28 



THOMPSON TYPE MACHINE COMPANY 



which passes through the slot in the Choker 

Cam (C-413) and move said Cam either 
forward or backward until the Choker Cam 
Lever Roller is in contact with the top of 
the Cam at the end nearest the operator. 
Fasten the hexagon head cap screw firmly. 

Once this adjustment is properly made 
you need never change it, no matter whether 
casting 48 point, 6 point or any other size ; 
nor need any change be made in its adjust- 
ment when casting leads, slugs or rule. 

To adjust the Choker Cam Lever Roller 
(C-966) so as to bring the Choker against 
the seat in the Choker Channel Bushing 
(C-580), with just enough pressure to pre- 
vent leakage, proceed as follows : Put the 
Matrix Carrier in position, lock the Pot in 
its casting position against the Mold and 
have all adjustments made as when ready 
to cast type and pull out the Pump Stop. 
Now turn the machine over by hand until 
the Choker Cam Roller (C-966) is in en- 
gagement with the Choker Cam (C-413) ; 
then loosen the hexagon Locknut (X-102-3) 
on the Choker Cam Lever Roller Adjusting 
Screw (X-114-7). Hook the Choker Trip- 
ping Tool (C-837) over the Choker Lever 
(C-854) right above the Choker Lever Link 
(C-527), press down on the end of the 
Choker Tripping Tool as far as it will go 
until the Choker (C-531), or (C-576), is 
pressed against its seat in the Choker Chan- 
nel Bushing just tight enough to prevent 
leakage of metal between the seat when 
the Pump drops. Now, with the small screw 
driver, first loosen the Choker Cam Lever 
Adjusting Screw (X-114-7), to make sure 
it is not too tight, and then tighten it until 
the Choker is pressed against its seat in the 
Choker Channel Bushing, just tight enough 
to prevent leaking to insure the casting of 
solid type, but without any unnecessary 
pressure or strain on the Choker or the 
Choker Lever as that would break the 
Choker (C-531) or the Choker Valve Lever 
(C-534). 

Old Style Choker Valve and Choker Cam 

If your machine is equipped with the old 
style Choker Valve (C-576), Choker Valve 
Fork (C-S32) and Choker Cam (C-519), all 



on plate 22, all adjustments, except that of 
the Choker Cam (C-519), are made the same 
as the new style Choker (C-531) explained 
under the preceding caption. The adjust- 
ment of the Choker Cam (C-519), however, 
must be changed for different size bodies. 

If you wish to cast type of a larger size 
than that for which the machine is set it 
will be necessary to move the Choker Cam 
(C-519) in a clock-wise (forward) direction 
just a little; when smaller size type is to be 
cast the Choker Cam must be moved a little 
in a counter clock-wise (backward) di- 
rection. 

Fitting Choker Point to Nozzle Plate 

After the metal is melted to its casting 
temperature compress the Choker Rod 
Spring (C-856), plate 1, by turning the 
Choker Spring Rod Adjustment Nut (C- 
530) to the left until the spring is tight 
enough to hold the Choker point seat firmly 
against the inside seat of the hole in Nozzle 
(H-575), with the Choker point protruding 
beyond the point of the Nozzle. Hook the 
Choker Tripping Tool (C-837), plate 20, 
over the Choker Lever (C-854), plate 1, at 
the point above the Choker Lever Link 
(C-527), moving the Tripping Tool (C-837) 
down and up a few times. This moves the 
Choker backward and forward, At the same 
time hold the Jet Box (J-597) or the Ladle 
(X-128-2) under the Nozzle to catch the 
molten metal. 

With the left hand hold the Nozzle Plate 
(H-639) in position against the Nozzle 
(H-575) and if the Choker Point extends 
through the hole in the Nozzle Plate dress 
off the point with a very fine file until it 
comes even with the face of the Nozzle 
Plate (H-639). It must not extend through 
the least bit or it will prevent the Choker 
point from closing when the pot is locked 
in casting position against the Mold ; neither 
must it be too short as that would allow 
metal to gather in the Nozzle Plate hole 
between the Mold and the Choker Point. 
This metal would chill while the type is 
ejected from the Mold and prevent the cast- 
ing of type with good faces and solid bodies.

Instructions for Attaching the Universal 
Choker Equipment to the Thompson 

Typecaster 

The equipment consists of: 

Plate 

1 Nozzle (H-575) 18 

1 Choker (C-531) 18 

1 Choker Channel Bushing (C-580) .18 

1 Choker Valve Lever (C-534) 18 

1 Choker Cam (C-413) 20 

(All Universal Style) 

. We also include a special plug to be used 
for removing the old bushings from the 
metal pot and for driving in the new one. 

To attach the above equipment to the 
Thompson machine proceed as follows : 
Drain of! the metal, remove the Thompson 
Nozzle and Choker in the usual way, and 
with the driving tool, or plug we furnish, 
drive the old choker valve bushing, which is 
in the forward end of the Channel, backward 
into the recessed portion of the channel from 
where it may be removed. Then again in- 
sert the Driving Tool into channel from 
which the forward Choker Valve Bushing 
has been removed, push it back against the 
rear Choker Valve Bushing and drive this 
last mentioned Bushing back into the Pump 
Well, from which it may be removed; this 
rear Bushing will require more force to 
drive back than the forward one because 
it has a shoulder at its forward end, which 
shoulder will be sheared off in driving this 
Bushing backward. 

Now clean the hole from which you have 
driven the Bushings, put a very little white 
or red lead on the new Universal Choker 
Channel Bushing, and with the plug we 
furnished drive it into position until the 
forward end of Bushing is back y%" from the 
front outer end of the Pot nozzle hole; if 
it is driven in any further the rear end of 
the Choker Channel Bushing will extend 
into the Pump Well and obstruct the down- 
ward movement of the Pump (P-572). Be 
careful to have the slot in the bushing at 
the top so that when it is in position the pin 
in the end of the new Choker Valve Lever 



(C-534) will pass through this slot, without 
rubbing on either side, to actuate the Choker 
(C-531). 

Now, with a Hand Drill, or a Breast Drill, 
drill a %" hole into the new Choker Chan- 
nel Bushing (C-580), plate 18, at a point in, 
or near, the rear corner of the recessed por- 
tion of the Pot through which the Bushing 
passes. This hole should be drilled as close 
to the outer diameter of the Bushing as 
possible, close to the wall of the recess; it 
should be shallow, not more than %" deep, 
care being taken not to drill into the Choker 
Hole of the Bushing. A piece of drill rod, 
or Bessemer rod, that fits the newly drilled 
hole should now be driven in the hole, which 
will prevent the bushing (C-580) from mov- 
ing when the Choker is operating. 

The new Choker (C-531), Nozzle (H-575), 
as well as the Choker Lever (C-534) are 
put into the melting pot in the same manner 
as the old style Thompson Choker and 
Choker Fork. 

Next, remove the old Thompson Choker 
Cam (C-519), place the new Choker Cam 
(C-413) (which is longer) in the same place, 
using the same screw to hold it in position, 
and adjust it so that when the choker is 
back against the Choker Seat,— or in other 
words, just as soon as the highest point of 
the Choker Lever Roller comes in contact 
with the top of the Choker Cam — the Choker 
is against the Choker Seat in the Choker 
Channel Bushing, at that instant, and not 
before, should the pump drop. Neither 
should it drop later, because if only the 
slightest turn of the cam shaft takes place 
after the Choker is seated against the seat 
in the Choker Channel Bushing before the 
pump drops a small drop of metal is apt to 
flow out of the nozzle into the jet channel 
of the mold and slightly chill before the 
pump drops. If this occurs the result is most 
apt to be a type with chilled face. That be- 
ing the case, why change the position of the 
Choker Cam at all, once it is set correctly? 

To make the above adjustments follow 
instructions given under the caption "Ad- 
justing Choker Cam and Choker Cam 
Roller".

Starting Machine for Casting Type 

Light the gas under the Metal Pot about 
forty-five minutes before starting to cast 
type. About three-quarters of an hour is 
usually required to bring the heat to the 
proper temperature. 

Before the Mold is adjusted it should be 
wiped absolutely clean and must be thor- 
oughly oiled and free from accumulation of 
dirt or metal; also make sure that all Oil 
Cups are filled. 

When casting from wide Thompson Ma- 
trix insert the wide Thompson Matrix 
Holder (G-928) in the Matrix Carrier; when 
casting from narrow Thompson Matrix in- 
sert the narrow Thompson Matrix Holder 
(G-929) in the Matrix Carrier. When cast- 
ing from a Linotype Matrix place an 8 
point Linotype Quad Matrix together with 
the Linotype Matrix Holder (G-721) along- 
side of the matrix in the Matrix Carrier. 

Determine the proper set which is shown 
on upper end of matrix and insert the neces- 
sary set blocks in opening made in Mold 
Body Plate by loosening Set Adjusting 
Liner Screw just right of mold facing ma- 
chine. Read carefully instructions under 
"Setwise Size of Type". 

Place Matrix in Matrix Carrier and put 
the Matrix Carrier on the machine. Then 
pull out knob in Matrix Carrier Lever (G- 
924) and raise the Matrix Carrier Fork (G- 
665) until it fits snugly under the handle 
of the Matrix Carrier. 

When the metal has been heated to the 
proper temperature hook the Choker Trip- 
ping Tool (C-837) over the Choker^ Lever 
(C-854) and press down on the end of the 
Choker Tripping Tool to make sure the 
Choker Point will move freely out of the 
hole in the Nozzle; this must be done to 
make sure the metal in the Nozzle is melted. 
If the metal is not thoroughly melted at this 
point the Choker Point will stick in the Noz- 
zle and break. Now wipe clean the face of 
the Nozzle ; also wipe clean the opening in 
Nozzle Plate and set the latter closely 
against the Mold. Swing Pot against Mold 
and lock it in casting position. 

Turn over Hand Wheel several times to 



make sure that all parts are moving freely. 

The Clutch Shifting Knob (S-804), plate 
5, is located on the right hand side of the 
machine base, directly above the Friction 
Wheel Controlling Knob (F-952). To shift 
the machine from neutral into low gear raise 
the Clutch Retaining Latch (S-866), plate 
4, thereby disengaging it from the middle 
annular groove in the Clutch Shifting Rod 
(S-810), plate 5, and press the Clutch Shift- 
ing Knob (S-804) inward to the limit. Then 
lower the Clutch Retaining Latch (S-866) 
engaging it in the right hand annular groove 
in the Clutch Shifting Rod (S-810). 

To stop the machine shift to neutral by 
reversing the above operation. 

Start the motor, allow it to run about half 
a minute, then with the right hand take hold 
of the handle of the Hand Wheel and turn 
it in its casting direction ; at the same time, 
with the left hand, raise the Clutch Shaft 
Retaining Latch (S-866) and pull out the 
Clutch Shifting Knob (S-804). 

The machine is now in high speed and 
ready to cast type of the smaller point sizes 
such as 6 Pt, 8 Pt., 10 Pt., 12 Pt., and 14 Pt. 
If type of the larger point sizes is to be cast 
lift up Clutch Shaft Retaining Latch and 
push in Clutch Shifting Knob. 

The Friction Wheel Controlling Knob 
(F-952), plate 5, is for the purpose of regu- 
lating the speed of the machine in conjunc- 
tion with the Clutch Shifting Knob, both 
located on the lower right hand side facing 
the machine near the Hand Wheel. This. is 
explained under "Casting Speeds". 

Pull out Pump Stop (P-682), on the upper 
left hand front facing the machine, only 
after all adjustments for casting are cor- 
rectly made. 

After running the machine for at least one 
minute turn on the water. When: casting 
type of the smaller bodies only a little water 
is required to keep the Mold cool, but when 
casting the larger sizes of type a good flow 
of water is necessary to keep the Mold suf- 
ficiently cool to insure a maximum casting 
speed. 

After making the first cast remove type 
from the Mold, break off jet and place type, 
with its nick up, alongside the Lining Stand- 



THOMPSON TYPE MACHINE COMPANY 



31 



ard on Aligning Gauge to ascertain whether 
it is of the proper alignment. If not, follow 
instructions under the caption "Making the 
Alignment/' 

Casting Speeds 

The speed at which type may be cast on the 
Thompson Typecaster is limited only by the 
length of time required to fill the water cooled 
Mold solidly with metal and give it sufficient 
time to chill before it is discharged. The time 
required to chill the metal varies with the size 
of type being cast. When any typecaster is 
operated at a speed too fast to permit the 
metal to solidly fill the mold chamber the 
result must be hollow type. 

While the following speeds are not the 
maximum at which some of the Thompsons 
in use are being operated they are the aver- 
age speeds suggested for best results under 
general conditions : 

6 point — 130 to ISO casts per minute 

8 point — 1 10 to 130 casts per minute 

10 point— 85 to 1 10 casts per minute 

12 point— 65 to 90 casts per minute 

14 point — 50 to 70 casts per minute 

18 point — 35 to 50 casts per minute 

24 point — 25 to 40 casts per minute 

*30 point — 18 to 30 casts per minute 

*36 point — 14 to 25 casts per minute 

*42 point — 1 1 to 20 casts per minute 

*48 point— 9 to 15 casts per minute 

*These sizes are cast with the use of the Stop Motion (see 
page 35) and as a cast is made only on every second revolution 
the R.P.M. should be twice the number of casts per minute. 

The first figures in the above table are the 
number of casts per minute of the em set 
characters ; the larger figures are those at 
which the thinnest characters, such as the 
lowercase "i" and "1" and the punctuation 
marks, should be cast. The speed of the ma- 
chine should be regulated between the mini- 
mum and maximum given in the table when 
casting the varying set sizes from the thin- 
nest to the widest characters. The operator 
will soon learn the speeds that will give the 
best results for the different sets. 

Before trying to set the machine for the 
proper speed at which to cast type the operator 
should thoroughly familiarize himself with the 



means for changing the speed of the machine 
as set forth in the following directions : 

The Thompson Typecaster is designed so 
that any speed between the high and low 
limits can be readily obtained. This is ac- 
complished by means of a friction drive and 
the high and low gear. 

The Friction Wheel Controlling Knob 
(F-952), plate 5, on the right side of the ma- 
chine base, controls the Friction Drive. Turn- 
ing the Friction Wheel Controlling Knob 
(F-952) in a clock- wise direction moves the 
Friction Wheel (F-805) towards the center 
of the Friction Plate (F-802) and reduces the 
speed of the machine. To increase the speed 
of the machine turn the Friction Wheel Con- 
trolling Knob (F-952) in a counter clock- 
wise direction. This operation moves the 
Friction Wheel (F-805) towards the rim of 
the Friction Plate (F-802). 

Never turn the Friction Wheel Controlling 
Knob (F-952) unless the power is on. If the 
Friction Wheel (F-805), plate 4, is moved 
while the Friction Plate (F-802), plate 4, is at 
rest a flat spot will be worn on the Fibre 
Friction Ring (F-655), plate 4, with the re- 
sult that the Friction Drive will not work 
properly. 

Small type should be cast at high speed; 
large type should be cast at low speed. Large 
type cannot be cast as fast as small type be- 
cause it takes longer for a large volume of 
metal to cool and solidify than for a small 
volume. If the machine is run faster than the 
interior of the type can solidify, the type will 
swell or explode upon being ejected from 
the Mold. The efficient water cooling sys- 
tem on the Thompson Machine makes it 
possible to run it faster on large sizes of 
type than any other machine of the kind. 

Type will have a "Frosty" face if cooled 
too quickly. It is, therefore, absolutely neces- 
sary that the water supply to the Mold is not 
too great. When the water flowing out of 
the Mold is lukewarm to the touch the 
proper amount is being supplied. 

Cleaning Choker Nozzle and Pump 

Swing back the Metal Pot and remove the 
Pump (P-572) by loosening the square head

THOMPSON TYPE MACHINE COMPANY 



Pump Lever Set Screw (X- 12 1-1) in the top 
o£ Pump Lever (P-537) and pull Pump Con- 
necting" Pin (P-549) outward and lift the 
Pump out of the Pot. If the Pump sticks in 
the Pump Well swing the Pump Links 
(P-705) upward, push a piece of round rod 
through the holes in Pump Links and turn 
the Pump (P-572) back and forth at the 
same time raising it up out of the well. 

Drop a small lump of mutton tallow or put 
a little oil on the metal and stir thoroughly 
until the dross is well separated from the 
metal ; then skim off the dross. This should 
be saved and sold to the metal refiners. 

Now place the Ingot Mold (E-551), plate 
22, under the Nozzle (H-57S) and drain all 
the metal from the Metal Pot by hooking the 
Choker Tripping Tool (C-837), plate 20, over 
the Choker Lever (C-854), plate 1, at the 
point above the Choker Lever Link (C-527), 
plate 1, and press down on the end of the 
Choker Tripping Tool until the metal flows 
freely out of the Nozzle into the Ingot Mold. 
The Ladle (X-128-2), plate 20, should be 
held before the Nozzle to guide the molten 
metal into the Ingot Mold. 

Now take out the Choker Lever Adjusting 
Screw (X-120-1) and remove the Choker 
Lever (C-534). 

Place the hexagon Box Wrench (E-993) 
on the Nozzle (H-575) and move it up and 
down until the Nozzle is loose. If the Nozzle 
sticks, loosen it by striking a sharp blow on 
the end of the Box Wrench (E-993). Clean 
all metal and oxides out of the inside of the 
Nozzle. 

Now take the Choker (C-531) or (C-576) 
out of the Pot and clean off all metal or 
oxides while it is still hot. 

With a stick of wood, clean out the Choker 
Channel, making sure no dirt is left in the 
Channel or the nozzle hole in the Pot, and 
immediately turn off the gas or electric cur- 
rent so the Pot will cool off. 

Immediately after turning off the gas or 
electric current, and while the Pot is still 
hot, clean out the Pump Well in the Metal 
Pot with a wooden stick and a rag. 

If there is an accumulation of oxides in 
the Nozzle or on the Choker it can be re- 
moved by heating them in the flame of a 



Bunsen Burner, or a Blow Torch, until they 
are a dull red (do not get them too hot), and 
then clean off the oxides. 

Grinding in Choker and Assembling 

Examine the Choker Channel Seat and the 
seat on the Choker. If either is not perfectly 
smooth they must be ground in by putting a 
little oil and fine emery flour, or some fine 
grinding compound, on the Choker Seat, in- 
serting the Choker in the Choker Channel 
and turning the Choker back and forth while 
pressing it against the Choker Channel Seat. 

If your machine is equipped with the new 
style Choker (C-531), plate 18, its seat is at 
the forward end of its shank about one inch 
from the Choker point. 

If your machine is equipped with the old 
style Choker Valve (C-576), plate 22, its seat 
is at the extreme rear end. 

To turn the new style Choker (C-531) 
back and forth while grinding in the seat 
hold the forward end of the Choker with the 
new Choker Seat Grinding Tool, being care- 
ful not to touch the point of the Choker 
(C-531) where it fits into the Nozzle hole, as 
bruising or damaging this point will cause metal 
to leak out of the Nozzle (H-575). 

The old style Choker Valve (C-576) can 
be turned back and forth by bending a piece 
of wire, about one-eighth of an inch in diam- 
eter, in the form of a loop with the two 
ends parallel and about half an inch apart. 
Insert the two ends of this wire loop in the two 
holes in the end of the Choker Valve (C-576) 
and with this wire as a handle turn the Choker 
Valve back and forth against the Seat. 

After grinding the Choker Channel Seat, 
as well as the Choker Seat, they must be 
wiped clean to be sure no emery or oil re- 
mains on them. 

The Point of the Choker (C-531) or 
Choker Valve (C-576) should be ground 
into the Nozzle (PI-575) with a little fine 
emery flour, or grinding compound, the same 
as was used for grinding in the Choker Seat. 
To do this proceed as follows: Be sure the 
Choker Point and the inside of the Nozzle 
are perfectly clean and free from metal or 
dross. Place the shank of the Choker (C- 
531) in. the small hole of the new Nozzle 



THOMPSON TYPE MACHINE COMPANY 



33 



Grinding Tool ; put a little fine valve grind- 
ing compound on the Choker Point and 
place the Nozzle Shank into the large hole 
of the Nozzle Grinding Tool. Holding the 
Nozzle and Grinding Tool together with the 
left hand, take hold of the Choker Shank, 
extending beyond the end of the Nozzle 
Grinding Tool, with the right hand and 
turn the Choker back and forth until a clean 
smooth seat is ground at and around the 
small hole inside the Nozzle and around the 
Choker Point. Now clean off all grinding 
compound from both the Choker and Nozzle. 

If the Pump (P-572), plate 18, was tight 
when it was taken out of the Well it was 
most likely due to oxides adhering to the 
Pump or the Pump Well wall. In that case 
put some thin oil on the Pump, place it in 
the Well and work it up and down with a 
turning motion; do not use emery as that 
may grind the Pump down too small. Then 
clean off oil thoroughly, both out of the 
Well and from the Pump. 

Now place the Choker in its Channel in 
the Pot, push it back as far as it will go so 
its point will not be in the Nozzle hole while 
the latter is being driven into the Pot; be 
sure the Nozzle Shank and the Nozzle hole 
in the Pot are absolutely clean. Place the 
Nozzle into the Pot, turn it back and forth 
a few times to make sure it will seat itself 
correctly when driven in. Put the Nozzle 
Driving Tool (H-979), plate 20, over the 
Nozzle and, with a medium sized hammer, 
strike the end of the Nozzle Driving Tool 
until the Nozzle is firmly seated in the Pot. 
Caution : — We wish to caution you to exer- 
cise care at all times when driving the 
Nozzle into the Metal Pot. If you will ob- 
serve the following rule the hole in the Pot 
into which the Nozzle fits will not become 
enlarged, as it does in case too much force 
is used in driving the Nozzle into position. 

Be sure the Nozzle hole in the Metal Pot 
is perfectly clean before the Nozzle is put 
into place. Also be sure the Pot is perfectly 
cold before the Nozzle is placed in it. When 
driving the Nozzle into position tap the 
driving tool slightly with the hammer, as it 
is easily held tightly on account of the taper 
of the hole in the Pot and the shank of the 



Nozzle that fits into it. A heavy blow will 
enlarge the Nozzle hole in the Pot and after 
a short time make the hole so large the Noz- 
zle will no longer fit tightly. 

If the Nozzle (H-S75) has been driven in 
straight its hole will be concentric with the 
Choker point and the Choker can be moved 
forward and backward without sticking in 
the Nozzle hole. Test this by putting the 
Choker Lever (C-534), or Choker Valve 
Fork (C-532), into place in the Pot and 
move Choker in and out by hand. If the 
Choker point sticks in the Nozzle it indi- 
cates that the latter was not driven in per- 
fectly straight. In that case ascertain which 
side of the Choker point binds in the Nozzle 
hole, then push Choker back out of the Noz- 
zle (H-S75) and with the Nozzle Driving 
Tool (H-979) against the Nozzle, tap it 
lightly with a hammer on that side at which 
the Choker point binds. Repeat this, if 
necessary, until the Choker point can be 
moved freely by hand in and out of the 
Nozzle. 

Now replace the Choker Valve Lever (C- 
534), or Choker Valve Fork (C-S32) ; fasten 
it in position with the hexagon head Choker 
Lever Adjusting Screw (X-120-1). 

Fill the Metal Pot (H-571) with metal, 
light the gas, or turn on the electric cur- 
rent, and heat up to proper temperature. 

When the metal is melted put the Pump 
(P-572) into the molten metal, but not into 
the Well. After the Pump is as hot as the 
metal it may be placed in the Well and con- 
nected by pushing the Pump Connecting 
Pin (P-549) through the holes in the Pump 
Links (P-705) and fastening it with the 
square head Pump Lever Set Screw (X- 
121-1). 

Adjusting Forward Position of Metal Pot 

It is usually necessary to readjust the for- 
ward position of the Metal Pot (H-571) 
after the Nozzle (H-575) has been replaced. 

There is a Rear Pot Adjusting Screw 
(X-114-11) in the Pump Lever Support 
(P-548) that should be slackened off by first 
loosening its Locknut (X-102-3) after the 
metal is hot, then the Pot swung against 
the Mold and locked in casting position. 
The two hexagon head Pot Screws (X- 






34 



THOMPSON TYPE MACHINE COMPANY 



120-3), which hold the Pot down on the Pot 
Yoke (H-S06), must be loosened just enough 
to allow moving the Pot forward without 
permitting it to be raised up. 

The Rear Pot Adjusting Screw (X-114- 
11) must then be brought against the Pot 
until it presses the Nozzle to a snug bearing 
against the Nozzle Plate and the Mold. Do 
not force it forward. There should be only 
just enough pressure to prevent leakage be- 
tween the Nozzle, Nozzle Plate and Mold. 
Then tighten the Locknut (X- 102-3) on 
Rear Pot Adjusting Screw (X-l 14-11) and 
tighten down the two hexagon head Pot 
Screws (X-120-3) on both sides of the Pot. 

Height of Type 

The dimension from the foot of the type 
to the surface of its face is called the 
"height-to-paper" ; the standard for this in 
the United States, Canada, England and 
Australia is 0.918 inch. 

The "depth-of-face" in the matrix is the 
depth of the hole in which the character is 
cast. 

Types of various sizes of bodies but all 
of equal height cannot be cast in one mold 
unless the "depth-of-face" in the matrices 
are all equal. 

The "height-to-paper" of the type cast 
equals the sum of the "height of Mold" and 
the "depth-of-face" in the Matrix. 

It is easily seen that, if a Matrix having a 
shallower "depth-of-face" is substituted for 
a deeper one, the "height-to-paper" will be 
less; if the "depth-of-face" in the matrix is 
more, the "height-to-paper" will be more. 
For this reason, a Mold of different height 
is required for each different depth-of-face" 
in Matrix when type of uniform height is to 
be cast. 

The depth of face in Thompson Matrices 
as well as Linotype and Intertype Matrices 
is uniform, namely, 0.043 inch. The height 
of the Thompson Mold for these Matrices 
is such that a blank cast therein measures 
0.875 inch high, adding 0.043 inch to 0.87S 
inch we have 0.918 inch, which is the Amer- 
ican and English standard "height-to- 
paper". 

The "height-to-paper" (overall height of 
the type) varies in different countries out- 



side the United States and Great Britain. 
The Thompson Type Machine Company 
can make the Mold so type may be cast of 
any desired predetermined height from 
matrices of any depth of face, provided, the 
following information is furnished : 

When matrices to be used on the Thomp- 
son Typecaster are obtained from some 
source other than the Thompson Type 
Machine Company we must know the depth 
of face in the matrix, and the overall height 
of type ("height-to-paper") the customer 
wants to cast ; or better still, furnish us with 
a sample matrix and a sample type, one for 
each size if the depth of face varies with 
different size bodies, and we will make the 
height of the mold, so type cast from the 
matrices to be used will give the customer 
type of the "height-to-paper" he wants. 

The Automatic Metal Feeder 

The Metal Feeder (E-418), plate 22, con- 
sists of a shallow round Pot, six inches in 
diameter at the top, with a spout. The 
chamber for the Gas Burner is formed by 
the circular wall of the Metal Feeder (E- 
418) extending downward six inches. The 
Gas Burner is attached to a rigid cross-bar 
inside the Burner Chamber. The Burner 
Chamber is open at its lower end and has 
holes in the circular wall at its upper end, 
immedately under the Feeder top, to allow 
free passage of air for proper combustion of 
gas at the Burner. 

A gas pipe with Stop Cock and fittings 
for connecting it to the gas supply pipe of 
the Metal pot Burner extends below the 
lower end of the Feeder. 

When the Metal Feeder is to be used with 
the Electric Pot it will be necessary to con- 
nect the Gas Burner, under the Feeder, to 
a gas supply pipe with a good gas cock on 
the end. To connect the gas cock with the 
Gas Burner use a piece of good gas tubing. 

The Feeder is hung on the back of the 
Pot Crucible (H-571) between the Pump 
Lever Support (P-S48) and the left hand up- 
right of the Pot Yoke (H-506) in which the 
Pot Yoke Handle (H-749) is fastened. 

Cold pigs of metal are placed on the top 
of the Feeder where they are liquefied and 
the molten metal flows through the spout 
into the Metal Pot (H-571) ; or the pig of 



THOMPSON TYPE MACHINE COMPANY 



35 



metal, after it becomes hot but before it is 
melted, may be pushed through the spout 
into the Metal Pot, where the final melting- 
can take place. A pig of hot metal will not 
chill the molten metal in the pot to any ap- 
preciable extent and the metal in the Pot 
may be quickly replenished, when it is low, 
without waiting for it to melt in the feeder. 
Another advantage of the Metal Feeder is 
that when casting large type, or six point 
and larger Slugs or Rule, the metal is used 
up so quickly that the Gas Burner under 
the Metal Pot (H-571) does not melt the 
metal fast enough to supply the amount 
used and keep the Metal pot filled with 
molten metal which is hot enough to pro- 
duce sharp faces on the type, or a good weld 
in the strip material. Here the Metal Feeder 
(E-418) becomes a necessity, The Gas 
Burner in the Feeder assists the Gas Burner 
under the Metal Pot in keeping the Pot full 
of metal at the proper temperature. 

We strongly recommend that every 
Thompson Typecaster be equipped with one 
of these Metal Feeders. 

The Stop Motion 

The Stop Motion is located on the right 
hand side of the Machine Base (B-800) be- 
tween the Clutch Shifting Knob (S-804) and 
the Friction Wheel Control Knob (F-952). 
With it in operation the output of type, 
borders and quads of the sizes larger than 
24 point can be increased at least fifty per 
cent The Stop Motion can be thrown into, 
or out, of operation in less than thirty 
seconds. 

Before throwing the Stop Motion into 
operation have Matrix Carrier in position 
and all adjustments made so the machine is 
ready for casting; be sure to have the Pump 
Stop (P-682) in its inward position to pre- 
vent metal from passing through the Noz- 
zle into the Mold. 

To throw the Stop Motion into operation, 
first raise the Clutch Shaft Retaining Latch 
(S-866) and press its end behind the flat 
Retaining Latch Spring (266), thereby dis- 
engaging the Latch from the middle annular 
groove in the Clutch Shifting Rod (S-810) 
and preventing it from falling down into any 
of the annular grooves in the Clutch Shift- 



ing Rod while the Stop Motion is in oper- 
ation. 

The Stop Motion Main Spring (264) must 
now be pushed over so its upper end bears 
against the outside of the Clutch Shifting 
Knob (S-804). This spring pushes the 
Clutch Shifting Rod (S-810) inward and 
throws the low gear into action. Now push 
upward the outer end of the flat Stop Motion 
Release Spring (265), until the short Stud 
on its inner end lowers the end of the Stop 
Motion Latch (254), thereby throwing the 
other end of the Stop Motion Latch upward 
into path of the Actuating Pin inside the 
Hand Wheel (S-541). This Hand Wheel 
Actuating Pin actuates the Stop Motion. 

After all the above adjustments are cor- 
rectly made pull out the Pump Stop (P-682) 
and the machine will now operate with an 
intermittent motion or dwell. The metal in 
the mold is chilled during the dwell so the 
type may be quickly discharged and the next 
type cast at much higher speed than would 
be possible without the Stop Motion. 

The Crank Pin (273) is located in the Stop 
Motion Disk (257) which is fastened to the 
outer end of the Friction Wheel Shaft (F- 
808). It actuates the Stop Motion Ratchet 
Wheel (255) by contact with the teeth of 
the Ratchet Wheel once during each revolu- 
tion of the Friction Wheel Shaft. 

When the machine is to be run at high 
speed, or when it is to be operated for sev- 
eral days for casting material in the smaller 
bodies, where the Stop Motion is not to be 
used, the Stop Motion Crank Pin (273) 
should be taken out of the Crank Pin Disk 
(257). This is easily done with a screw 
driver ; the removal of this pin prevents the 
operation and wear of the Stop Motion 
parts, thereby prolonging its life. 

Troubles and Remedies 
Causes and remedies for hollow spaces 
and type of small setwise dimensions are 
discussed here. 

The cause of trouble of this character is 
usually a combination of two or more ad- 
justments being improperly made. Thin 
spaces and characters are usually the most 
difficult to cast solid. This is because cer- 
tain laws of physics that have only a slight 
effect when casting type of large setwise 



36 



THOMPSON TYPE MACHINE COMPANY 



dimensions become prominent when casting 
thin type. The length of time required for 
the type to cool is directly proportional to 
the ratio between the volume of metal en- 
tering the mold and the area of inside walls 
of the mold. In the case of thin spaces and 
characters of small set-wise dimensions, the 
area of the walls of the mold cavity is large 
while the volume of the metal required to 
fill the cavity is comparatively small. For 
this reason, the ratio is small and the time 
of cooling is very short. In order, therefore, 
to cast solid spaces and type of small set- 
wise dimensions the metal must be injected 
into the mold as quickly as possible and the 
temperature of the mold must not be kept 
too low. In order to accomplish this the 
following should be done: 

1. (Increase the speed of the machine. 
•This results in the complete casting oper- 
ation being done very quickly and does not 
allow much time for cooling. 

2. Decrease water and oil supply. This 
allows the temperature of the mold to go 
up with the result that the incoming metal 
will not be cooled too quickly. 

3. Increase the temperature of the metal 
in the pot from 25 to 30 degrees above nor- 
mal casting temperature. Because the 
amount of heat that must be conducted from 
the metal by the mold, and the water cir- 
culating through it, is greater, the time re- 
quired for the type metal to solidify will be 
greater. 

4v Increase the Pump Spring pressure 
slightly. This will cause the metal to be 
forced into the mold more positively and 
with greater speed and will therefore allow 
the mold to be filled before the metal has 
had too much time to cool. The pressure 
should not be increased excessively, es- 
pecially for the smaller body sizes. Exces- 
sive spring pressure is just as bad as too 
little pressure. A little experience will make 
it possible for the operator to correctly judge 
the correct amount of pump spring pressure 
to give the best results. 

5. Carefully adjust the metal pot to the 
right or left so that there is a maximum 
opening of the nozzle to the mold. If the 
opening is too small metal will enter the 
mold too slowly with the result that it may 



start cooling before the mold cavity has 
been completely filled. 

From the above, it will be seen that the 
casting of narrow spaces and type of small 
set-wise dimensions is dependent generally 
upon heat and upon the time required for 
cooling of the metal as it enters the mold. 
It is well, therefore, to keep these matters 
well in mind while casting narrow set 
material. If any unusual difficulty is en- 
countered it is often easily overcome by try- 
ing to imagine what is taking place in the 
mold and then locating the difficulty by 
logical reasoning. 

When Type Is Hollow 

Improper seating of the Choker on the 
Choker Seat may be the cause of hollow 
type. Leakage at the Choker Seat may be 
due to improper seating because of wear. In 
this case it will be necessary to regrind the 
valve to a seat. This will be found necessary 
only after the machine has been in use for 
some time. Do not grind the valve unless 
it is absolutely necessary and then proceed 
in accordance with the directions given in 
this book under the heading, "Grinding in 
Choker and Assembling." 

Hollow type will also be produced by the 
machine if the temperature of the metal is 
too high. On the other hand, if the tem- 
perature of the metal is too low, the metal 
will not be sufficiently fluid to flow into and 
completely fill the mold with the result that 
the face will not be sharp and perfect. See 
"Temperature of Metal." 

Hollow type may be the result of incor- 
rect location of the Metal Pot. If the Metal 
Pot is too far to the right or left the open- 
ing in the Nozzle Plate (H-639) may be ob- 
structed by part of the Jet Ejector (J-893) 
or the Vertical Mold Blade (V-612 or V- 
613) to such an extent that it is impossible 
for sufficient metal to enter the mold. Cor- 
rect method of making left and right Metal 
Pot adjustment is given under the caption 
"Sidewise Adjustment of Metal Pot."

to the opening of the mold. This may be 
due to an insufficient supply of water cir- 
culated through the mold or may be the 
result of running the machine too fast. A 
combination of the above may also be the 
seat of the trouble. If you are experiencing 
trouble of this kind read "Casting Speeds." 

The Cause of and Remedies for Squirts or 

Splashes 

A Thompson Typecaster will never 
"squirt" or "splash" unless the metal is too 
hot, or through improper adjustment of its 
various parts, or because of dirt or foreign 
matter being lodged between any of several 
parts an opening is left through which me- 
tal can escape. 

If the Vertical Mold Blade (V-612) or 
(V-613) does not bear evenly against the 
end of the type mold an opening may be 
left that will result in a squirt. When mak- 
ing this adjustment care should be taken to 
see that no dirt or foreign matter becomes 
lodged between the parts. It is clear that 
if anything should get between the parts 
they cannot be brought into contact with 
one another. The result is an opening. See 
"Adjusting Vertical Mold Blade" for method 
of making correct adjustment. 

Dirt or any foreign matter on the front 
side of the matrix will prevent it from seat- 
ing properly upon the mold. This may 
cause a "squirt." 

The Matrix Carrier Cam Lever Spring 
(G-926) which is held between the Matrix 
Carrier Lever (G-924) and the Matrix Car- 
rier Cam Lever (G-925) acts as a cushion 
for the Matrix Carrier. It is the pressure 
of this spring that holds the Matrix Carrier 
against the mold. Tightening the Matrix 
Carrier Cam Lever Screw (G-923) com- 
presses the Matrix Carrier Cam Lever 
Spring (G-926) and consequently moves 
the Matrix Carrier further away from the 
mold. If this is tightened too much, the 
Matrix Carrier will be pulled back so far 
that an opening will be left between the 
Matrix and the mold with the result that 
there will be a "squirt" if the machine is 
run that way. See "Adjusting Matrix Car- 
rier Lever" for proper adjustment of the 
Matrix Carrier Cam Lever Spring (G-926). 



If the Jet Block (A-12) or the Mold Top 
Block (A-ll) are not down on the Jet Ejec- 
tor or the Body Piece, either due to impro- 
per adjustment or due to dirt or foreign 
matter having lodged between them, there 
will be an opening through which metal 
will escape. For the proper method of ad- 
justing these parts see "To Change Jet 
Ejectors" and "To Change Mold Body 
Pieces." 

Dirt or foreign matter on the front side 
of the Nozzle Plate (H-639) will prevent its 
seating.properly against the mold. This will 
leave an opening through which metal may 
be forced. Dirt or foreign matter on the 
Nozzle (H-S75) or in the part of the Nozzle 
Plate (H-639) which receives the Nozzle, 
will prevent a tight joint being made be- 
tween these parts with the result that 
there may be a "squirt". If the Metal Pot 
is not tightly locked up, or if the adjust- 
ment of the Metal Pot is not proper, the 
Nozzle Plate (H-639) will not completely 
fill up the space between the Nozzle (H-575) 
and the mold with the result that an open- 
ing will be left through which metal may 
be forced. For instructions as to making 
the proper metal pot adjustments, see "Fit- 
ting Choker Point To Nozzle Plate" and 
"Adjusting Forward Position of Metal Pot". 

The cause of a "squirt" is always quite 
easily located by looking for the place from 
which the metal escaped. 

The Causes of Fins and the Remedies 

A Fin on a piece of type is a miniature 
squirt. The causes and remedies are iden- 
tical. Dirt lodged between parts of the 
mold or improper mold adjustments are al- 
ways the cause. Whenever a Fin appears 
on any part of the type or on the jet it is 
positive evidence that there is an opening 
between parts of the mold. The seat of the 
trouble can always be located by observing 
on what part of the type or its jet the fin 

is. 

If a Fin appears on the left hand side of 
the type as it comes from the machine it 
indicates that there is an opening between 
the Vertical Mold Blade (V-612) or (V- 
613) and the mold. To remedy, clean the 
parts thoroughly and adjust according to 



38 



THOMPSON TYPE MACHINE COMPANY 



the instructions under the caption "Adjust- 
ing Vertical Mold Blade". 

Horizontal fins on either the top or bot- 
tom of the right hand side of the type as 
it comes from the machine indicates that 
there is an opening between the Mold Body 
Piece and either the Mold Top Block (A- 
11) or the lower part of the mold. The 
remedy is, to remove the Body Piece and 
the Jet Ejector, thoroughly clean them and 
the parts of the mold with which they come 
in contact and then replace the parts and 
adjust them in the manner described under 
the captions, "To Change Jet Ejectors" and 
"To Change Mold Body Pieces". 

A Fin on the shoulder of the type indi- 
cates that there is an opening between the 
matrix and the mold. This may be due to 
dirt or metal being lodged on the face of 
the matrix or on the part of the mold with 
which the Matrix comes in contact. It may 
also be due to improper adjustment of the 
Matrix Carrier Lever Screw (G-923). In 
this connection see "Adjusting Matrix Car- 
rier Lever". 

A Fin at the base of the Jet indicates that 
there is an opening between the Nozzle 
Plate (H-639) and the mold. This may be 
due to the Metal Pot being improperly 
locked up or to dirt or to improper Pot ad- 
justment. In this connection read, "Ad- 
justing Forward Position of Metal Pot". 

When Type Is Too Wide Set- Wise 

If type is oversize in the set-wise dimen- 
sions there are three possible causes. First: 
There may have been an error in making 
up the combination of Set Blocks. Second : 
Dirt may have become lodged between the 
set blocks or they may not be tightly clamp- 
ed. If trouble is experienced with type that 
is oversize in set it is always well to remove 
all of the Set Blocks, thoroughly clean 
them and replace, being sure to turn the 
Set Adjusting Liner Screw (M-934) snug, 
not too tight, with the fingers. Never use 
a wrench or pliers on this screw. Third: 
If either of the above is not the cause of 
the difficulty, dirt or metal on the side of 
the Matrix Holder or the end of the Set 
Adjusting Liner (M-90S) may be the cause. 
Sometimes the trouble is due to faulty ad- 



justment of the Vertical Mold Blade (V- 
612) or (V-613) or to dirt or metal having 
become lodged between the Mold and the 
Vertical Mold Blade (V-612) or (V-613). 
The remedy is to remove and thoroughly 
clean the Vertical Mold Blade, being sure 
to carefully clean all other parts with which 
the Vertical Mold Blade comes in contact. 
Then replace and adjust in accordance with 
the directions under "Adjusting Vertical 
Mold Blade"- 

When Type Is Oversize in Body Dimension 

Type that is oversize in the body dimen- 
sion is the result of dirt being lodged be- 
tween the Mold Body Piece and the Mold, 
or of the Mold Top Block (A-ll) not being 
far enough down. It must be in actual 
close contact with the mold Body Piece. 
The best remedy for type oversize in body 
dimension is to remove the Mold Body 
Piece, thoroughly clean it and the Mold 
cavity, replace and carefully adjust in ac- 
cordance with the directions given under 
"To Change Mold Body Pieces". 

When Type Is Too High To Paper 

If the height of the type is oversize it is 
due to the matrix not seating properly 
against the mold. This may be due to dirt 
being lodged on the face of the matrix or 
on the mold. The best remedy is to thor- 
oughly clean the parts. It may also be due 
to improper adjustment of the Matrix Car- 
rier Lever Screw (G-923). In this connec- 
tion see "Adjusting Matrix Carrier". 

What Causes Defective Type Faces? 

One of the commonest type face defects 
is that known as a "frosty face". This is 
caused by sudden cooling of the metal as 
it enters the mold. The first few pieces of 
type cast on a cold machine usually have 
frosty faces. This difficulty will disappear 
after the mold has had time to warm up 
unless it is because too much water is cir- 
culating through the mold. If the water 
leaving the mold is warm to the touch it 
is properly adjusted. If it is cold, cut down 
the supply and the difficulty will disappear. 
If the mold is flooded with oil, imperfect 
faces will also result. There is a difference 
in the appearance of frosty faces and faces 



defective because of too much oil. Too 
much oil prevents the hot metal from flow- 
ing evenly over the surface of the mold 
cavity and the matrix. With a little ex- 
perience it will be easy to recognize type 
made imperfect because of excessive oil. The 
remedy is to cut down the oil supply and 
run the machine, casting type, until the 
oil is worked out of the mold. Care should 
be taken not to cut down the oil supply 
so far that the mold will not be sufficiently 
lubricated. To do so is liable to cause dam- 
age to the mold by cutting and scoring. 

If the type is cast with too low a tem- 
perature of the metal it will be solid but 
will be imperfect in the face and body. One 
of the most noticeable characteristics of 
type cast with metal that is too cold is that 
the edges of the type body and type face 
will not be sharp- When metal is too cold 
it will not flow freely. The result is that it 
will not flow into all of the corners and 
crevices. As soon as metal that is low in 
temperature strikes the matrix or walls of 
the mold cavity it is suddenly cooled be- 
yond the point where it will flow. The re- 
sult is that the body and face of the type 
will not have a smooth, plane surface but it 
will be uneven. 

Type with uneven surfaces and rounded 
edges is often the result of worn out or 
poor metal. Tin in type metal makes it 
fluid. If the metal has been overheated, or 
has been used over a period of time, the 
proportion of tin becomes low through a 
process of oxidation. It may also become 
low due to skimming the metal from the 
top of the Pot. The metal should always 
be separated from the oxides or dress by 
putting a piece of mutton tallow into it and 
stirring well. Dross or Oxides always ap- 
pear as a black powder and not as thick, 
more or less unfluid metal. See "Practical 
and Metallurgical Points Regarding Care 
and Handling of Metal". The remedy is to 
replace the defective metal with new or to 
add the missing ingredient to the defective 
metal. 

When Metal Leaks Out of Nozzle 

Leaking of metal out of the Nozzle is 
liable to happen during the time that the 



metal is being melted. It does not indicate, 
however, that anything is wrong. If the 
leak does not stop after the metal is melt- 
ed and up to casting temperature, hook the 
Choker Tripping Tool (C-837) over the 
Choker Lever (C-854) at a point above the 
Choker Lever Link (C-527) ; hold the Jet 
Box (J-597) or the Ladle (X-128-2) in front 
of the Nozzle (H-575) and pull downward 
on the end of the Choker Tripping Tool. 
This will open the Choker and allow the 
metal to run from the Nozzle (H-575). 
Then suddenly release the pressure on the 
end of the Choker Tripping Tool, thereby 
allowing the Choker to close suddenly. 

The foregoing operation will allow any 
chilled metal in the Nozzle (H-575) to es- 
cape. - If the leak does not stop it indicates 
that the Choker is not properly seating in 
the Nozzle. This may be due to insufficient 
pressure on the Choker Rod Spring (C- 
856). To increase the pressure on this 
spring turn the Choker Spring Rod Adjust- 
ing* Stud Nut (C-530) in a counter-clock- 
wise direction. Care should be taken not 
to tighten the Choker Rod Spring (C-856) 
excessively. To do so will produce undue 
strain on the parts and may damage the 
forward seat in the Nozzle (H-575). About 
Y§ f compression of the Choker Rod Spring 
(C-856) is usually sufficient. 

It is also possible that the Nozzle (H- 
575) has not been driven in straight. To 
remedy, relieve all of the pressure on the 
Choker Rod Spring (C-856) by turning the 
Choker Spring Rod Adjusting Nut (C-530) 
in a clock-wise direction and give the Noz- 
zle (H-575) a light tap with the Nozzle 
Driving Tool furnished with every machine. 
Apply the pressure of the tool at a point 
opposite to the point at which the metal 
escapes. The point of the Choker should 
move freely in and out of the opening in 
the Nozzle without the pressure of the 
Choker Rod Spring (C-856). If it does not, 
it indicates that the Nozzle (H-575) is not 
driven in straight and it will leak. 

If any of the above means of stopping 
the leak prove ineffective it is pretty clear 
that the Nozzle (H-575) and the Choker 
(C-531) or (C-576) are hindered in their 
operation by an accumulation of oxides ; 






or that the Choker needs grinding. To 
correct these difficulties proceed as directed 
under "Cleaning Choker, Nozzle and 
Pump". If the desired result is not then 
accomplished, proceed to grind the choker 
valve as directed under "Grinding In Cho- 
ker and Assembling". 

The Cause of Choker Sticking 

A sticking Choker (C-531) or (C-576) is 
invariably caused by dirt or oxides becom- 
ing lodged in the Nozzle (H-575) and on 
the Choker. To remedy, proceed as direct- 
ed under the caption "Cleaning Choker, 
Nozzle and Pump". 

When The Pump Sticks. The Remedy 
As in the case of a sticking Choker Valve, 
a Pump (P-572) that sticks is the result of 
a collection of Oxides or dirt in the Pump 
Well or on the Pump (P-572). To correct, 
follow the directions given under "Clean- 
ing Choker, Nozzle and Pump". 

Gas Burner Fails To Generate Enough 
Heat To Raise Metal in Pot To Re- 
quired Temperature. What Is 
Remedy ? 

If the burner fails to generate enough 
heat to raise the metal to the proper tem- 
perature, it is evident that the supply of 
air to the burner is not sufficient to burn 
all of the gas. This fault is easily remedied 
by properly adjusting the Burner Air Reg- 
ulating Plate (H-S18J4). This part is lo- 
cated immediately under the Burner Mixer 
(H-518). To adjust, turn Burner Air Reg- 
ulating Plate (H-518^) to the right, or to 
the left, until the flame is blue. If the 
flame is all yellow, or if it shows up yellow 
at the top, it indicates that there is not suf- 
ficient air entering the Mixer to burn all the 
gas. If the Burner Air Regulating Plate is 
turned so that too much air enters the 
Mixer, the flame will "strike back" into the 
Mixer. In this case it will be necessary 
to extinguish the flame and re-light after 
adjustment has been made to decrease the 
amount of air entering the Burner Mixer. 
A few trials at the adjustment of the burner 
will thoroughly acquaint the operator with 
the operation of the burner so that no fur- 
ther difficulty will be experienced. 



Mold Works Tight. What Is The Remedy? 

The mold may work tight as a result of 
the lack of oil or as the result of being 
set too tightly at the beginning. If the 
mold runs tight as the result of insufficient 
oil supply the result is liable to be serious. 
Insufficient oil is the cause of a cut mold. 
Hardened steel parts, such as the molds are 
made of, will always cut if run together 
without oil. The remedy is obviously to 
supply the oil. Care should be taken, how- 
ever, not to supply an over-amount. To do 
so will result in imperfect faces. See "What 
Causes Defective Type Faces". 

The Mold may actually be set too tight 
at the beginning and still work freely. It 
works tight as the result of the expansion 
of the mold parts due to heat, the Mold 
being cool at the time it is originally set. 
After a few casts have been made the in- 
coming metal will heat up the mold suf- 
ficiently to cause the several parts to ex- 
pand and work tight. The remedy is to 
stop the machine and reset the mold as di- 
rected under "Type Mold Adjustments". 

What Is The Cause and Remedy For 

Changing Type Alignment While The 

Machine Is In Operation? 

When the Thompson Typeeaster leaves 
the factory all adjustments are properly 
made. If, however, the parts of the Matrix 
Carrier should work loose through wear the 
proper adjustment can be easily made as 
follows : Remove the Matrix Carrier (A-8) 
loosen the Slotted Nut in the center of the 
Graduated Knob, then turn the Graduated 
Knob to the left until the Matrix Carrier 
Adjusting Block is almost out of the Matrix 
Carrier (A-8). The small headless Set 
Screw that passes through the back of the 
Matrix Carrier Adjusting Block, against 
the split Bronze Bushing, must now be 
tightened to compress the split Bronze 
Bushing just enough so there will be no 
lost motion of the Matrix Carrier Adjust- 
ing Screw in the split Bronze Bushing. 

This operation compresses the Matrix 
Carrier Block Bushing and makes it fit the 
Matrix Carrier Adjusting Screw more close- 
ly. The adjustment is correct if the Matrix 







THOMPSON TYPE MACHINE COMPANY

Carrier Graduated Knob can just be turned 
with the fingers. Do not tighten the set 
screw so much that it is necessary to use 
a pin wrench to turn the Matrix Carrier 
Graduated Knob. 

What Is The Cause and Remedy For a 

Friction Drive That Slips and Fails 

To Pull The Machine? 

The cause of a slipping Friction Drive is 
usually an excess of oil. Inside of the rim 
of the Friction Wheel (F-805) a groove has 
been provided to catch any oil that may 
be thrown from the shaft or bearing by 
centrifugal force. If this is wiped out oc- 
casionally with a piece of cotton waste or 
rag no difficulty in this respect will be en- 
countered. If, however, this difficulty is 
experienced, it can be easily corrected by 
wiping the face of the Friction Plate (F- 
802) and the Friction Ring (F-655) with 
gasoline or benzine. This will remove all 
of the oil from the parts and eliminate the 
trouble. After long use the Friction Ring 
(F-655) may become worn with the result 
that the pressure of the Friction Plate (F- 
802) against the Friction Ring (F-655) may 
not be sufficient to pull the Machine. In 
order to correct this the pressure on the 
Friction Plate Spring may be increased by 
turning the Friction Plate Spring Tension 
Nut (F-827) in a clock-wise direction. Care 
should be taken not to make the spring 
pressure excessive. The pressure should 
only be enough to just drive the machine. 
If the tension is too great the pressure of 
the Friction Plate (F-802) against the Fric- 
tion Ring (F-655) will be excessive with 
the result that flat spots are liable to be 
worn on the Friction Ring (F-655). In this 
case the friction drive will fail to operate 
satisfactorily and the only remedy then is 
to remove the Friction Wheel Assembly 
from the machine, place it in a lathe and 
turn the fibre Friction Ring (F-655) in 
order to remove the flat spots. When this 
is necessary follow instructions under the 
caption "How To Remove The Friction 
Wheel". With ordinary care of the parts 
in question no repairs should be necessary 
for years. Thompson Typecasters have been 
in use for long periods without the neces- 



sity of removing any of the Friction Drive 
Parts. 

General Hints 

When through with the day's work swing 
the Metal Pot away from the Mold only far 
enough so the center toe of the Pot Yoke 
still rests on the planed part on the Base 
Top. 

When leaving the machine with the pot 
swung away from the mold be sure that the 
choker valve is properly closing the nozzle. 
Otherwise when the pot is lighted up the 
metal will flow out of the nozzle until the 
metal heats enough to allow the valve to 
close. 

Allow the machine to stand a few minutes 
with the pot connected before starting work 
to permit the mold to become heated suf- 
ficiently to make a good cast. Now swing 
the pot away from the mold; then hook the 
Choker Tripping Tool (C-837) over the 
Choker Lever (C-854) and move the Choker 
back and forth, as explained under the cap- 
tion "Starting Machine for Casting Type," 
to make sure no chilled metal remains in 
the nozzle. This should be done whenever 
the machine has been at rest for half an 
hour or more. 

Do not turn machine over and permit the 
Pump Cam Lever (P-524) to drop when 
the pot is disconnected. The blow may 
break the lever. If the Pump Stop (P-682) 
beneath the lever is pressed inward when 
the lever reaches its full upstroke it will 
support the lever and prevent damage. 

If the old style Choker Cam (C-519) is 
set too far forward, or too far back, it will 
not operate the choker valve in proper time 
to allow the pump to force metal into the 
mold. It can be readily shifted to find the 
best location. 

There are adjusting screws for the right- 
hand Matrix Carrier Slide (G-671). If the 
Matrix Carrier is not snug on the slides it 
will affect the alignment of the type. Do 
not touch the adjustment of the left-hand 
M'atrix Carrier Slide (G-670). It is for as- 
sembling purposes only, and must never be 
changed outside the factory. 

There is a split bronze bushing and a 
small screw for adjusting same on the 



42 



THOMPSON TYPE MACHINE COMPANY 



Matrix Carrier aligning screw. This is for 
the purpose of taking up play in the screw. 
The nut in the top of the knurled knob can 
also be tightened to prevent the alignment 
changing. 

The Type Stripper Spring (R-679) must 
be set so as to engage all type as they are 
ejected. If it does not do so the type may 
pull back in the mold and cause a "squirt." 
When it is acting properly it will show a 
slight cut in the forward edge of the type 
about one point back. It should be set so 
as to project through the shoe about -£% of 
an inch. 

The Type Nick Cutters (R-680) must not 
be turned over and should be set to cut but 
a slight groove in the type. Four different 
combinations are possible; one cast nick 
only, the forward cutter only and the cast 
nick, the rear cutter only and the cast nick, 
and both cutters and the cast nick. 

Never use pliers on the knurled screw 
heads. If wrenches or pliers were intended 
to be used the heads would not have been 
knurled. 

Do not leave the machine with the Jet 
Ejectors (J-893) exposed to the flame of the 
metal pot. Turn the machine so as to draw 
the ejector into the mold while it is not 
running. 

If it becomes necessary to sharpen the 
Type Trimming Knives (T-726 and T-727) 
rub them across the surface of a large oil 
stone, all teeth bearing at once on the stone. 
Grind off the back of the teeth so the cutting 
edges will be only one-sixty-fourth of an 
inch wide. 

Narrow Thompson Matrices are used in 
the same manner as wide Thompson Mat- 
rices. It is only necessary to use the proper 
Matrix Holder. The "C" block and, in ad- 
dition, the number of Set Adjusting Blocks 
making up the points indicated on the back 
of the matrix are placed behind the slug of 
the Set Adjusting Liner. 

When the machine is equipped with the 
Micrometer Set Adjusting Device the Style 
"B" Matrix Holder for wide and narrow 
Thompson Matrices must be used. 

The matrix carrier is pressed resiliency 
against the mold by a cushion spring locat- 
ed between the two parts of the Matrix 



Carrier Lever. The adjustment to press the 
matrix against the mold tightly is made by 
turning the screw which passes through the 
spring. The nut on the other end of the 
screw must be kept tight and, when proper- 
ly adjusted, the concave Washer under the 
head of the screw will be free when the car- 
rier is pressed against the mold. 

The tension of the friction drive can be 
increased by turning in on the threaded col- 
lar on the Friction Plate Shaft behind the 
machine. The tension of this, as of all other 
parts, should be only sufficient to do the 
work. 

The mold can be quickly cleaned with- 
out removing it by raising the Mold Top 
Block and Jet Block by means of the eccen- 
tric, then disconnecting the Mold Body Plate 
Pin (M-933) and taking off the Mold Body 
Plate Outside Locknut (M-707) and the 
Mold Body Plate Inside Locknut (M-673) 
and removing the Set Adjusting Screw 
(M-674). The Mold Body and Jet Ejector 
are next removed and the Set Adjusting 
Liner Clamping Screw taken out. This 
Liner (M-905) and the Mold Body Plate 
(M-942) can now be drawn backward and 
removed from the mold, when the mold in- 
terior is made readily accessible for clean- 
ing. 

Friction Plate and, Friction Wheel 

The Friction Wheel (F-80S), which has 
a Fibre Ring (F-655), is mounted on the 
Friction Wheel Shaft (F-808) ; its periphery 
bears against the face of the Friction Plate 
(F-802) which is mounted on the end of the 
Friction Plate Shaft (F-833). 

The Friction Plate (F-802) is held in 
contact with the Friction Wheel (F-805) by 
the Friction Plate Spring (F-824). 

If the Friction Drive slips it may be due 
to oil or grease on the Friction Plate and 
the Friction Wheel, or the pressure of the 
Friction Plate against the Friction Wheel 
may require adjusting. 

With a clean cloth, saturated with gaso- 
line or benzine, thoroughly clean off all 
grease from the Friction Wheel (F-805), 
the Fibre Friction Ring (F-655) and the 
face of the Friction Plate (F-802), then wipe 
perfectly dry with a clean cloth.

If, after cleaning, the Friction still slips 
it may be necessary to tighten the tension 
on the Friction Plate Spring (F-824) to in- 
crease the pressure of the Friction Plate 
against the Friction Wheel. 

To tighten the tension on the Friction 
Plate Spring (F-824) use the Pin Wrench 
(E-981) and turn the threaded Friction 
Plate Spring Tension Adjusting Nut (F- 
827), which is on the Friction Plate Shaft 
Bearing (F-822) behind the machine, to the 
right only a little at a time until the pres- 
sure of the Friction Plate (F-802) against 
the Friction Wheel (F-805) is just enough 
to prevent slipping. The tension of this, as 
of all other parts, should be only sufficient 
to do the work. 

Also carefully examine the periphery, or 
face, of the Fibre Friction Ring (F-655) to 
see if there are any flat spots on it. If there 
are the Friction Wheel (F-805) must be 
taken out of the machine and the Fibre 
Ring faced off true in a lathe. 

How to Remove the Friction Wheel 

To remove the Friction Wheel (F-805), 
plate 4, proceed as follows : First loosen 
the Friction Plate Spring Tension Adjust- 
ing Nut (F-827) on the Friction Plate Shaft 
Bearing (F-822) until all pressures against 
the Friction Plate Spring (F-824), plate 4, 
is entirely removed. Then cut a piece of 
wood just a little longer than the distance 
between the face of the Friction Plate 
(F-802) and the edge of the side door open- 
ing in the Machine Base (B-800), about 
four inches long will do. Force this piece 
of wood between the face of Friction Plate 
and door opening to hold the Friction Plate 
away from contact with the Friction Wheel 
(F-805). 

Now turn the Friction Wheel (F-805), 
plate 4, very slowly until, by looking 
through the lower front door opening of the 
Base (B-800), you can see the small end of 
the Taper Pin (X-119-4) which passes 
through the hub of the 4-inch Speed Gear 
(S-820) and the Friction Wheel Shaft (F- 
808). Then with a piece of brass rod, placed 
against the small end of the Taper Pin 
(X-119-4), drive the Pin out of the Speed 
Gear by striking the other end of the brass 



rod with a hammer ; be careful not to bruise 
the end of the Taper Pin or it will not pass 
freely through the hole in the Speed Gear. 

Next take out the Friction Shaft Bearing 
Set Screw (X-114-4), which holds the Fric- 
tion Shaft Bearing Bushing (F-817) in the 
hole in the left hand side of the Base 
(B-800) ; loosen the Set Screw (X-114-5) in 
the Friction Wheel Shaft Collar (F-861). 
Place a round piece of wood against the end 
of the Friction Wheel Shaft (F-808) on the 
Hand Wheel side of the base and, with a 
heavy hammer,, drive the Shaft toward the 
other side; this drives out the Bushing 
(F-817) with the Shaft. 

The Shaft may now be pulled out from 
the left hand side of the Base, care being 
taken to hold the Gears, Shaft Collar and 
Friction Wheel from falling on the floor of 
the Base and injuring them as the Friction 
Wheel Shaft (F-808) is pulled out of these. 

After the Shaft is out the Friction Wheel 
will rest on the inside bottom of the Base, 
with its Shaft bearing held in the hole of 
the Friction Wheel Shifter Yoke (F-946). 
Now take out the three Friction Wheel 
Shifter Yoke Retaining Ring Screws (X- 
105-1) and lift off the Friction Wheel Shif- 
ter Yoke Retaining Ring (F-967). The 
Friction Wheel (F-805) can now be taken 
out of the Base, then placed on a Mandrel 
and the face of the Fibre Ring (F-655) 
turned off true in a lathe. 

Practical and Metallurgical Points Regard- 
ing Care and Handling of Metals 

Type metals are alloys of Tin, Lead and 
Antimony. The finest working type metal 
is that alloy of correct formula which most 
closely approaches a state of chemical pur- 
ity. It is not commercially possible or prac- 
tical to produce a metal that is 100 % chem- 
ically pure. But every user of a Thompson 
Type, Lead and Rule Caster should endeav- 
or to use only such metal as will give the 
best results. The best type metal obtain- 
able is none too good for a machine that is 
built with the accuracy and precision of the 
Thompson. Remember that the service re- 
sults of a good metal will be in proportion 
to the care you give it in casting and re- 
melting. 






44 



THOMPSON TYPE MACHINE COMPANY 



There are two fundamental reasons why 
type metals deteriorate while in use : 

(1) The unbalancing of the proportions 
of Lead, Tin and Antimony, or, in other 
words, the changing of formulae. 

(2) The introduction of impurities into 
the metal while it is being remelted and 
worked. 

The unbalancing of the Lead, Tin and 
Antimony results generally from three 
causes : 

(1) Skimming of metal when it is too 
cold. When molten type metal is main- 
tained near the solidifying point there is a 
tendency for the tin and antimony to segre- 
gate at the surface. Skimming then takes 
off a greater amount of these two important 
ingredients. This is especially the case with 
metals having a high Tin and Antimony 
content. 

(2) Oxidation or Burning of Metal. Tin 
has a greater affinity for oxygen than An- 
timony, while Antimony has a greater affin- 
ity for oxygen than Lead. It follows, there- 
fore, that when metal is overheated the 
oxidation or dross formation, which results 
from contact of air and surface metal in 
the pot, is greater than when the metal is 
run at its proper temperature. Therefore, 
in order to reduce this oxidation to a mini- 
mum and keep the metal in good condition 
for the longest possible time it should be 
worked, both in the Typecaster and in the 
remelting pot, at the lowest temperature 
at which the best type can be cast. 

(3) When a plant is using more than one 
grade of metal they may become mixed. 
The utmost care should be taken, therefore, 
not to mix the different grades, as such 
mixing will unbalance the proportion of Tin, 
Lead and Antimony and change the for- 
mulae. 

Impurities 

Carelessness on the part of the workman 
when he throws the old metal into the re- 
melting pot may result in zinc etchings, iron 
shavings or filings, sweepings or other im- 
purities, which may also contain arsenic, 
being introduced and melted with the metal 
which will surely deteriorate the good metal 
mixture. Zinc causes the metal to be slug* 



gish and gives poor faces and bodies. Zinc 
will also attack the pump, choker and other 
parts of the typecaster pot mechanism. 

Arsenic is an impurity often present in 
virgin, as well as in used, metal and cannot 
be removed in the printing plant. If the 
metal contains the impurity in excess of 
one-eighth of one per cent the only remedy 
is to dispose of it to the refinery in exchange 
for new, clean, free-flowing metal. 

Formulae 

The following percentages of ingredients 
for metals for different classes of work will 
be found to give excellent service results: 

Hard Foundry Type Metal for Roman 
Faces : 

Tin 13% 

Antimony 23% 

Lead . . 64% 

100% 

Metal for Italic and other faces that re- 
quire Kerning or that Overhang, and for 
Metal Rule: 

Tin 9% 

Antimony 12% 

Lead 79% 

100% 

Metal for Spaces, Quads, Leads, Slugs 
and Rules: 

Tin 6% 

Antimony 12% 

Lead 82% 

100% 

In combining the lead, tin and antimony 
it is necessary to first melt the antimony 
at a high temperature so as to liquefy it 
thoroughly. Then the lead and tin should 
be melted separately and the antimony 
mixed with the lead and tin and the com- 
bination should then be thoroughly stirred 
from time to time, over a period of three 
hours, before the metal is finally cooled 
into pigs. The purpose of this is to see that 
the antimony is properly combined with the 
other metals because the percentage of 
antimony in this metal has been materially 
reduced beyond the usual percentage for 









SBBERMHH^HHni^BBHMHHa^HMHM 



THOMPSON TYPE MACHINE COMPANY 



45 



type metal and this antimony must, there- 
fore, be thoroughly combined with the 
other ingredients so that the type will not 
suffer through the reduction in the anti- 
mony. 

The Re-Smelting An Important Detail 

One detail, which is probably of the 
greatest importance and which has been 
most grossly neglected, is the care given 
the metal during re-melting and pigging. 
Many buyers are especially, particular to 
purchase fine type metals, yet they over- 
look the fact that Metal is no better than 
its care. 

As soon as the mass of type has been 
turned into liquid in the re-smelting furnace 
examine the surface residue and imme- 
diately skim off any brass matrices or rules ; 
these contain zinc and are, therefore, detri- 
mental to type metals. 

It is an excellent idea occasionally to 
boil the metal, which is done in the follow- 
ing manner: While the temperature of the 
metal is still low, just after it has reached 
a state of fluidity,, attach a raw potato or 
a piece of green wood to the end of an iron 
rod. (This should be attached with iron 
wire and under no circumstances should 
brass or copper wire be used.) Plunge the 
potato or wood into the bottom of the 
metal, holding it there for five or ten 
minutes. The agitation or bubbling of the 
metal, which is called boiling, will bring 
impurities to the surface, break up the 
crystallization of antimony (which has 
been taking place while the metal has been 
previously remelted) and refine the metal. 

Allow the metal to heat up until hot 
enough to brown an inserted strip of paper 
before skimming off the dross. Clean dross 
will harm nothing and as it acts as a non- 
conductor of heat it holds the heat in the 
metal, thus hastening its heating and 
economizing on time. 

Then (if there is no danger of fire from 
adjacent walls) throw a half teacupful of 
ordinary machine oil or tallow upon the 
metal and quickly ignite it. While the 
flame burns stir it vigorously in contact 
with the dross. Since dross is oxygen com- 
bined with metal the flame will consume 



much of the oxygen and liberate the metal 
it held, which will pass back into the pot. 

If enough stirring and oil flame are 
applied the dross will be turned from a 
heavy metallic skimming into a fine brown 
powder, which should be skimmed into the 
dross drums and the pigs immediately 
poured. This will insure the pigs being cast 
from metal that has just been thoroughly 
stirred. 

If, during the work of pouring pigs, the 
workman is interrupted and it becomes 
necessary to leave the job, when going 
back to the job the metal should be again 
thoroughly stirred before doing any further 
pouring. If metal is allowed to remain 
liquefied without stirring the tin and anti- 
mony will rise to the top, like cream upon 
milk, and pigs poured from separated metal 
will cause trouble. 

Instructions for Operating the Lead and 
Rule Casting Device 

In changing over from casting type to 
casting leads, slugs or rules, it is necessary 
to remove the type-casting equipment and 
replace this with the Lead, Slug and Rule 
Attachment. 

If the machine is equipped with the 
attachment for trimming type on all four 
sides (shown on Plates 27 and 28), and 
this is in place on the machine it must also 
be removed. When this is necessary follow 
instructions under caption, "Removing 
Trimming Attachment and Adjusting Ma- 
chine for Casting Spaces and Quads". 

First remove Matrix Carrier (A-8), Noz- 
zle Plate (H-639) and Type Receiving Shoe 
(A-14). Then loosen the Vertical Mold 
Blade Adjusting Screw (V-646), plates 1 
and 2, the head of which, in some models, 
is located in the end of the Mold Stand 
(N-502) immediately under the Type Stick, 
while in other models it is located on the 
front of the Mold Stand immediately to the 
left of the Matrix Carrier Slide (G-670). 
Now loosen the Hexagon Nut on the 
knurled head Upper Adjusting Screw (V- 
684) that passes through the top of Vertical 
Mold Blade Cam Lever (V-525), raise the 
Vertical Mold Blade Lever Yoke (V-511) 
and slide the Vertical Mold Blade Lever 




46 



THOMPSON TYPE MACHINE COMPANY 



(V-512) to the left as far as it will go, this 
draws the Vertical Mold Blade Lifting 
Block (V-615) out of the recessed portion of 
the Vertical Mold Blade (V-612 or V-613) ; 
then lift out the Vertical Mold Blade. 
(CAUTION : On the right hand end of the 
Mold Stand (N-503) immediately under the 
Mold (A-13) is the Mold Locating Screw 
(M-983). This screw is NOT to be dis- 
turbed when the Mold is removed from the 
Mold Stand as it is adjusted at the factory 
to hold the Mold in its correct position in 
relation to the Matrix Carrier). Next loosen 
the small screw that passes downward 
through the back right hand end of the Mold 
Body Plate (M-942) and withdraw the Mold 
Body Plate Connecting Pin (M-933) ; this 
disconnects the Mold Body Plate Adjusting 
Screw (M-674). 

Now loosen the knurled head Mold Block 
Adjusting Screws (M-683 and M-693) and 
the Jet Block Adjusting Screws (J-650 and 
J-691), which pass through the Mold Stand 
Cap, until the ends of these Adjusting- 
Screws are even with the underside of Mold 
Stand Cap. Insert large end of Pin Wrench 
(E-981) in the hole in the Mold Top Ad- 
justing Eccentric (M-898) and Jet Block 
Adjusting Eccentric (J-897) and turn each 
Adjusting Eccentric to the right until the 
Mold Top Block and the Jet Block are 
brought up against the Mold Stand Cap. 
Now insert the sharp end of the Body Lift- 
ing Tool (M-982) in the groove on under- 
side of Mold Body (M-894), raising it by a 
slight downward pressure on the outer end 
of the Mold Body Lifting Tool. Push the 
Mold Body forward toward the left, take 
hold of it with the fingers and remove it 
from the Mold. Remove the Jet Ejector in 
the same manner. 

Remove the Mold Body Plate (M-942) by 
drawing it to the right out of its bearings 
in the Mold. With the small screw driver 
remove the four Mold and Jet Block Lift- 
ing Stud Nuts (M-939), next take out the 
four Mold Stand Cap Screws (N-872) and 
lift the Mold Stand Cap (N-910), with the 
left hand, high enough to enable you to re- 
move the Mold and Jet Block Lifting Yokes 
(J-937). 

The Mold can now be lifted out of the 



Mold Stand. Should the Mold fit very tight 
in the Mold Stand care must be exercised in 
removing it, using only a piece of brass rod 
pr a hard wood stick for a lever to raise the 
Mold out of its position. Place the Mold on 
the bench and lift out the Mold Top Block 
(A-ll) and the Jet Block (A-12). Be very 
careful not to damage any of the parts in 
doing this, using only a piece of brass rod 
or a hard wood stick for a lever to raise 
the parts out of the Mold. Flush all the 
Mold Parts with benzine or gasoline and 
wipe them clean ; also run a piece of wire in- 
to the oil hole that runs from the front of 
the Mold Bottom Block (A-9) through it 
to the lower felt pad, to make sure oil will 
flow freely through it to lubricate the side 
of the Vertical Mold Blade (V-612 or V-613) 
and the end of the Mold (A-13) where they 
come in contact one with the other. 

After thoroughly cleaning all the Mold 
Parts wipe them with a piece of clean cloth 
dipped in fine lubricating oil and assemble 
the Mold ready to put it on the machine. 

The Pin, 5/16" diameter, the forward end 
of which is located about 2 inches below the 
Matrix Carrier Rail, must now be driven 
back and out of the Mold Stand and the 
Bronze Shoe used with the Type Mold taken 
out. Now place the special Bronze Vertical 
Mold Blade Shoe (1093) in position, using 
the special flat headed pressure screw in 
place of the knurled head screw which is 
used with the Type Mold, then put the 
Lead, Slug and Rule Mold Vertical Blade 
(1092) into its place in the Mold Stand, but 
do not adjust the Vertical Blade until the 
Mold is in position. 

NOTE: When the Vertical Mold Blade 
Adjusting Screw (V-646), plates 1 and 2, is 
located on the front of the Mold Stand im- 
mediately to the left of the Matrix Carrier 
Slide (G-670) it need not be replaced with 
another one as the same Adjusting Screw 
is used for both the Type Mold Vertical 
Mold Blade and the Lead, Slug and Rule 
Mold Vertical Mold Blade. 

Place the Lead, Slug and Rule Mold into 
the Mold Stand, making sure the Mold, 
Vertical Mold Blade and Mold Stand are 
perfectly clean, and push it as far to the 
left as it will go. Be sure the bottom of the 



THOMPSON TYPE MACHINE COMPANY 



47 



/*S 



Mold is down flat on the Mold Stand, the 
left hand end of the Mold should now abut 
firmly against that part of the Mold Stand 
from which the Type Receiving Plate (R- 
630) has been removed, while the other end 
of the Mold must be under the head of the 
Mold Locating Screw, which is in the right 
hand end of the Mold Stand. 

If there is any play of the Mold between 
the head of the Mold Locating Screw and 
the higher part of the Mold Stand at its 
other end it will be necessary to tighten the 
Mold Locating Screw so that the Mold can- 
not be moved backward or forward ; it is 
rarely however that this adjustment need be 
made because the length of the Lead, Slug 
and Rule Mold is usually made that it will 
fit between the parts above mentioned with- 
out any extra adjustment. Place the Lead, 
Slug and Rule Mold Stand Cap (1082) in 
position on the Mold Stand and use the four 
fillister head cap screws that are used on 
the Type Mold Stand Cap ; tighten these 
screws firmly. 

Now adjust the Vertical Mold Blade 
(1092) by first tightening the special flat 
headed Adjusting Screw in the left hand end 
of the Mold Stand, or the regular Vertical 
Mold Blade Adjusting Screw located in the 
front of the Mold Stand, so the Bronze Shoe 
will hold the Vertical flat against the end of 
the Mold, sufficiently tight to prevent any 
leakage of metal between the Vertical and 
the Mold while casting strip material. 

Next, connect the Vertical Mold Blade 
Lever (V-512) and turn the Hand Wheel 
until the Vertical is at its highest point. In 
this position the upper end of the Vertical 
should be about .002" (a paper thickness) 
below the Rule Matrix when it is in casting 
position. This adjustment is made with the 
two screws, one of which passes through 
the top downward and. the other through 
the bottom upward, of the Vertical Mold 
Blade Cam Lever (V-52S). The ends of the 
screws must be tightened and locked firmly 
against the projecting Lug of the Vertical 
Blade Lever (V-512) after the adjustment 
has been made. If the Vertical is set too 
high it will strike the Rule Matrix and 
damage it; if too low, there will be a leakage 



of metal between the Upper end of the Ver- 
tical Mold Blade (1092) and the Matrix. 

After the above adjustments have been 
correctly made, the hexagon head Adjust- 
ing Screw (V-984) must be very carefully 
adjusted by first releasing and then tighten- 
ing it until it gently presses the Vertical 
Mold Blade Supporting Plug (V-960) 
against the lower right hand side of the 
Vertical Mold Blade (1092), as explained 
under the caption, "Adjusting Vertical Mold 
Blade". Be very careful not to force the 
Brass Plug (V-960) too tight against the 
Vertical Mold Blade (1092) or it will push 
the lower end of this Vertical Mold Blade 
too far to the left. If it is too loose it will 
allow the Vertical Mold Blade to shift too 
far to the right and throw its upper end out 
of proper contact with the end of the Lead, 
Slug and Rule Mold, thereby casting a fin 
or burr on the Jet of the strip material be- 
ing cast. 

Release set screws in bearing of Cam 
Lever Shaft (K-585) and drive shaft to the 
right far enough to mount the Cutter Cam 
Lever (1341) and the Stud (1342) in left 
hand bearing. Tighten the screw in the 
right hand bearing to prevent the Cam Lev- 
er Shaft (K-585) from shifting; also tighten 
the screw in the left hand bearing to hold 
the Cutter Cam Stud (1342) firmly in its 
place. 

Place Lead, Slug and Rule Receiving 
Block (1104), Plate 10, in position, using 
the two knurled screws (R-696) taken from 
the Type Receiving Shoe (R-648) to hold it 

Connect Body Blade Link (1004), Plate 
10, to Mold Body Plate Adjusting Screw 
(M-674). Turn machine over by hand and 
set the Mold Body Plate Inside Locknut 
(M-673) on the Mold Body Plate Adjusting 
Screw (M-674) so the rear wall, or cross 
piece, of the Mold Body, when at the end 
of its forward stroke, can be seen projecting 
not more than two points beyond the jet 
opening in the Mold Back Wall where the 
Metal enters the Mold. This adjustment is 
of the utmost, importance, because, unless 
it is made exactly right, it will be impossible 
to cast strip material with a good weld or 
fuse at the joint, especially 2 point leads or 
2 point rule. When this adjustment is cor- 



48 



THOMPSON TYPE MACHINE COMPANY 



rectly made, lock the Mold Body Plate In- 
side Locknut (M-673) on the Mold Body 
Plate Adjusting Screw (M-674) by tighten- 
ing the Locknut (M-707) firmly against it. 
Adjust the back stroke of the Body Blade 
Link so that the section cast will be about 
1" long for Leads and Slugs, and 21/32" 
long for Rule. Set the Back Stop Finger 
(1161), plate 10, by first loosening the Screw 
that passes through the lower forward side 
of the Stroke Adjusting Back Stop Finger 
(1161) against the Stroke Adjusting Finger 
Guide Stud (1088), plate 10, and then turn- 
ing the Stroke Adjusting Thimble (1085) 
until the Back Stop Finger (1161) is in con- 
tact with the Body Blade Link (1004) when 
the Mold Body is in casting position at the 
end of its backward stroke. Lock the Back 
Stop Finger (1161) securely by tightening 
the Screw against the Stroke Adjusting 
Finger Guide Stud (1088). Adjust the long 
Knurled Nut (M-708) so it will just hold 
the Body Blade Link (1004) against the 
Back Stop Finger (1161) without spring- 
ing it while the Mold Body is in its cast- 
ing position, then place the Special Knurled 
Nut, furnished with the Lead and Rule 
Equipment, on the end of the Adjusting 
Screw (M-674) and with it lock long 
Knurled Nut to prevent it from working 
loose. 

NOTE: When the machine is equipped 
with the Micrometer Set Adjusting Device 
the Back Stop Finger is not furnished with 
the Lead and Rule equipment because the 
Micrometer Set Adjusting Device is used 
instead of the Back Stop Finger. Adjust- 
ment of the back stroke of the Body Blade 
Link is made much easier with the Mi- 
crometer Set Adjusting Device than is 
possible with the Back Stop Finger. 

When these adjustments are correctly 
made there will be considerable play on 
each side of the upper end of the Mold 
Body Lever (M-520) between the Locknut 
(M-673) and the long Knurled Nut (M- 
708), but the length of section cast must 
be as above stated in order to obtain good 
results. 

Replace Foot Plow Bracket (T-976) with 
the Knife Block Set Screw Bracket (1090), 
plate 11, which fits in the same slot in the 



Mold Stand, and adjust screw running 
through upper end of said Bracket (1090) 
so the end of this screw bears against the 
lower end of the Trimming Knife Block 
(1105), plate 11, just enough to hold it from 
being forced backward as the strip material 
is trimmed in passing the Trimming Knife 
(1106), plate 11, 

The Trimming Knife (1106) on the Trim- 
ming Knife Block (1105) must be adjusted 
so that it will trim the jet even with the 
surface of the strip without removing any 
metal other than the jet, not cutting any 
deeper at either the upper or lower edge. 
This Knife is correctly adjusted at the 
factory. 

Should it become necessary to adjust the 
Trimming Knife (1106) remove the Trim- 
ming Knife Block (1105) and adjust the 
Knife so that its cutting edge will be ex- 
actly even, or level, with the upper and 
lower edges of the inside of the Block 
(1105). This Block is slightly recessed the 
width of rule height so the strip material 
will pass through freely after it has passed 
the Trimming Knife. 

By setting the cutting edge of the Knife 
even with the inside edges on each side 
of the recessed portion of the Block, the 
Trimming Knife (1106) will project .001" 
beyond said recessed portion and trim the 
strip material correctly. 

To place the Cutter Operating Cam 
(1131), plates 10 and 11, on the end of the 
Cam Shaft (K-579) from which you re- 
moved the Trimming Cam (49) proceed as 
follows: Turn Cam Shaft (K-579) in the 
casting direction very slowly until the 
Pump Lever (P-524) drops into the re- 
cessed portion of the Pump Cam (P-510), 
then turn it backward until the Pump 
Lever abuts firmly against the straight side 
of the Pump Cam (P-510) opening. Next, 
place the Cutter Operating Cam (1131) on 
the end of the Shaft by pushing the dowel 
pins that are in the Cam (1131) into the 
holes in the end of the Cam Shaft (K-579) 
so as to bring the point, or highest part, of 
the Cam (1131) to point toward the rear 
of the machine. Now pass the %"-20 screw 
through the center hole in the Cam and 
screw it tight.

The Cutter Cam Roller Bar Guide (1329), 
plate 11, must now be attached to the base 
at the place provided for it, the narrow end 
of the Cutter Cam Roller Bar (1353), plates 
10 and 11, placed therein and the other end 
attached to the Cutter Cam Lever. 

There are two Bracket Brace Rods, each 
made up of two pieces (1164 and 1165) and 
a Turnbuckle (1166), plates 10 and 11. 
They are marked at both ends to show 
where they are to be attached. Alongside 
of the holes in the side of the base numbers 
are stamped to correspond with the num- 
bers stamped on the end of the Bracket 
Brace Rods, while the numbers stamped 
on the other ends of these Rods designate 
their position under the Cutter Bracket as 
follows : That end of the Bracket Rod with 
the figure "0" is to be attached to the 
Bracket where it is marked "0" near the 
screw hole in the bracket; it is the Upper 
Rod. The end of the Lower Rod marked 
"1" is to be attached to the Bracket below 
the Upper Rod and the other ends of the 
Bracket Brace Rods must be attached to 
the upper base so the numbers "2" and "3" 
correspond with the same numbers 
stamped near the holes in said Upper Base. 
Attach the cutter to left hand end of 
Mold Stand by first putting the Screws 
through the holes in Cutter Bracket Plate 
into the holes in Mold Stand; while doing 
this a support of some kind must be placed 
under the Cutter Bracket (1334), plates 10 
and 11, at its extreme left hand end to pre- 
vent straining or springing the Cutter 
Table (1336). Now adjust the three nuts 
on the three screws in left hand end of 
Mold Stand and the Bracket Brace Rods 
(1164) and (1165), that run from the Cut- 
ter Bracket to the side of the Machine Base, 
so that the Bracket Table is level and the 
Gauge Rod (1351), plates 10 and 11, to 
which the Gauge Finger (1375) is fastened 
will move freely back and forth without 
binding. Place the %" Finger Guide Stud 
(1088), plate 10, in the hole provided for 
it in the right hand end of the Mold Stand 
(N-502) and fasten it in position by tighten- 
ing the hexagon nut firmly against the Mold 
Stand (N-502) ; then put the %" Stroke 
Adjusting Stud (1087), plate 10, to which 



is attached the Backstop Finger (1161) and 
the Stroke Adjusting Thimble (1085), into 
the hole above the Y%" Finger Guide Stud 
(1088) and lock it in place by tightening 
its hexagon nut against the Mold Stand. 

Put the glass barrel Oil Cup, furnished 
with the Lead, Slug and Rule Equipment, 
in position on top of the Mold Stand Cap 
(1082), plate 11, and place the wire beneath 
it so it will feed oil, about one drop a min- 
ute, onto the upper end of the Vertical 
Mold Blade, from which the oil will flow 
into the Mold Jet Cavity and lubricate the 
Vertical Mold Blade (1092) where it is in 
contact with the Mold. 

Set the Gauge Finger (1376), plate 10, 
to cut any desired length of strip material 
required by adjusting it the required dis- 
tance from the Cutter Knife so that the 
Gauge Finger, as the strip material comes 
in contact with it, will actuate the Cutter 
through the Gauge Rod (1351). 

Put Nozzle Plate (H-639) in place and 
lock the Pot in casting position. This is 
important. Then loosen the adjusting screw 
behind the Pot and the two screws which 
hold the Pot in place on the Yoke, also 
the screw which holds the Choker Lever 
in place. Push the entire Metal Pot to the 
left, or to the right, far enough so the jet 
opening in the Mold will pass directly 
across the center of the hole in the Nozzle 
Plate when the Pot is locked against the 
Mold in its casting position. It may be 
necessary to make this adjustment several 
times before it is exactly right, but it must 
be correct in order to insure the successful 
fusing, or welding, of the sections as they 
are cast. This pot adjustment is made with 
the two very large head screws in the Pot 
Yoke, one on each side of the Pot. Be sure 
to tighten all screws that hold Pot and 
Choker Valve Lever before beginning to 
cast. 

Several strips of Leads, Slugs and Rule 
are furnished with each equipment. To get 
a start in casting it is necessary to insert 
a short strip of this material of the proper 
size into the open end of the Mold to" pre- 
vent molten metal from being forced out 
of the Mold cavity.

A Stripper Cam (1108) is located in a 
slot in the end of the Knife Block (1105) 
and is held in position by a knurled head 
Pin which passes through a hole, from the 
top, in the Knife Block (1105) and through 
a hole in the Stripper Cam (1108). A flat 
Stripper Cam Spring (1109), plate 11, actu- 
ates the Stripper Cam. 

This Stripper Cam prevents the strip 
material from being drawn back into the 
Mold Body during the backward stroke of 
the Mold Body. 

Care must be taken that this Stripper 
Cam is in its operating position while in- 
serting the strip material necessary to be- 
gin casting Leads, Slugs or Rule. 

While inserting the strip of material 
through the Cutter from the Cutter Table 
(1336) into and through the cavity between 
the Trimming Knife Block (1105) and the 
Receiving Block (1104), it is necessary to 
hold the Stripper Cam (1108) back by push- 
ing the end of it, that extends beyond the 
end of the Trimming Knife Block (1105), 
back against the Stripper Cam Spring 
(1109) with a thin piece of brass or the 
small screw driver, far enough to permit the 
strip being inserted to pass freely between 
the eccentric end of the Stripper Cam 
(1108) and the inner wall of the Receiving 
Block (1104) and into the Mold. 

After the strip of material is in casting 
position allow the Stripper Cam end to 
come forward; the eccentric end of the 
Stripper Cam (1108) will then hold the 
Lead, Slug or Rule being cast from return- 
ing or being pulled back into the Mold. 

To cast Rule: Replace Lead or Slug 
Mold Body with Rule Mold Body of the 
desired size. Place Rule Matrix, plate 11, 
in position, being sure those parts of the 
Mold, called the Matrix Chamber, into 
which the Matrix fits are perfectly clean. 
Insert the fillister head screw through 
front of Mold into the threaded hole in the 
side of the Matrix, drawing it up only 
slightly, then turn knurled head screw 
(1083) down on top of Matrix, but only 
tight enough to hold the Matrix snugly 
against the top of the Mold Body. Now 
tighten the fillister head screw from the 
front of Mold to draw the Matrix firmly 



against the flat side of the Matrix Chamber. 
Do not fail to put a few drops of oil into 
the oil groove on the forward side of the 
Matrix where it is held against the Matrix 
Chamber. 

When changing the bodies from one 
thickness to another (as, for example; from 
2 point to 4 point), it is necessary to change 
the Liner that fits under the stationary 
knife and the Liner that fits into the Re- 
ceiving Block ( 1 104) , so the opening 
through which the strips pass will be the 
correct size in both the Receiving Block 
and between the stationary and movable 
knives on the cutter. These Liners are 
marked to designate the sizes for which 
they are to be used. 

Although Linotype metal may be used 
for casting strip material, better results are 
obtained by using a metal mixed according 
to the following formula : 

Tin 6% 

Antimony 12% 

Lead 82% 



100% 



The temperature of the metal when cast- 
ing leads and slugs should be not less than 
650 degrees Fahrenheit, but when casting 
2 point rule with hair line face the tem- 
perature should be about 800 degrees 
Fahrenheit. The speed for casting 2 point 
leads and 2 point rule should be not less 
than 80 revolutions per minute to insure 
good fusing and good sharp face ; this speed 
must be reduced as the size (thickness) 
being cast is increased. 

Lock the Metal Pot in its casting position 
for a few minutes before beginning to cast, 
in order to heat the Mold sufficiently so 
the sections will weld, or fuse. Be sure to 
shut off the water during the time the Mold 
is getting warm, but turn on and regulate 
the flow of water to get the best results 
after the machine is started. 

Trimming, Kerning and Bearding Type on

ing, Kerning and Bearding attach- 
ment appear on plates 27 and 28.

As the type is ejected from the Mold by 
the Body Blade it is pushed to the left into 
the Vertical Carrier where it is held firmly 
between the Vertical Mold Blade Type Sup- 
port (2) and the Vertical Mold Blade 
Bridge (6) by two Stripper Spring Pins 
that pass through the Bridge. It is then 
carried upward past the Stationary Jet 
Breaker (64), where the Jet is removed, 
until the Vertical Mold Blade with its type 
Support and Bridge are in casting position. 
While in this position the next type is cast 
in the mold. 

During the upward movement of the type, 
the Extractor Slide (14) moves to the right, 
bringing the Extractor close to the Vertical 
Mold Blade. The Extractor remains in this 
position until the Vertical Mold Blade de- 
scends to its normal position bringing the 
type inside of the Extractor in position to 
enter the Type Receiving Shoe. The Ex- 
tractor Slide (14) then moves to the left 
when the Extractor pulls the type into the 
Receiving Shoe. At the same time, the 
type that was cast while the one about to 
be trimmed was in its highest position, is 
ejected from the mold. 

As the type is pulled through the Re- 
ceiving Shoe the face end of the type passes 
between the Upper and Lower Dressing 
Knives (21 and 13), where it is trimmed 
before it reaches the left end of the Re- 
ceiving Shoe. Here it is held firmly between 
the Upper and Lower Receiving Shoe by 
two Stripper Spring Pins. While in this 
position the Vertical Dressing Knives (27 
and 28) descend and trim the type on both 
sides. 

Now the Extractor Slide (14) moves to 
the right, but the trimmed type still re- 
mains in position, where its sides were 
dressed, until the next type that was cast 
is pulled into the Type Receiving Shoe. 
Before this next type reaches the end of 
the Receiving Shoe where it is to be dressed, 
the last type dressed is pulled out of the 
way by the Extractor Slide Trip Latch 
(17). 

All adjustments for casting and dressing 
type are correctly made on each machine 
before it leaves the factory. Samples of 
type dressed and cast will be found in the 



Receiving Shoe on the machine. We sug- 
gest that the operator closely study the 
movements of the different parts of the 
Trimming Attachment before making 
changes to another size body or set. 

Extractors 

Four Slide Extractors are furnished with 
each equipment. The shortest one must be 
used when dressing 6, 8 or 10 point type; 
the next size is for dressing 12, 14 or 18 
point; another size for dressing 24, 30 and 
36 point, and the longest one for dressing 
42 and 48 point. Each one is marked with 
figures to designate the various sizes of 
type for which it is to be used. One of these 
Extractors is fastened with a screw to the 
right, or inner end of the Extractor Slide 
(14). 

Adjustments 

When changing from one size body to 
another, first swing back the Metal Pot, 
loosen the fillister head slotted locking 
screw that passes through the upper end 
of the Vertical Mold Blade Type Support 
(2) and turn the Knurled Head Adjusting 
Screw (5), that projects beyond the ex- 
tension, to the left until the Vertical Mold 
Blade Bridge (6) is raised as high as it 
will go. Next remove the Upper Type Re- 
ceiving Shoe (20), which is held in position 
by one knurled head screw. Remove the 
Extractor Slide (14) if the Extractor on 
the end is to be changed for one that is 
longer or shorter. The Extractor Slide is 
removed by taking hold of it with the right 
hand and, with the left hand, pulling the 
upper end of the rear Bell Crank (61) to 
the left until the extending pin that con- 
nects the Slide with the Bell Crank is pulled 
out of the slot in the upper end of said 
Bell Crank (61), 

Before putting the Upper Receiving Shoe 
(20) back on the machine, the Mold Body 
(M-894) must be changed in the usual man- 
ner, the Matrix placed in position in the 
Carrier and all adjustments made for cast- 
ing type. Now lock the Pot in its casting 
position and cast two or three type by 
hand. Swing back the Metal Pot away 
from the Mold. Next, place two type on 



52 



THOMPSON TYPE MACHINE COMPANY 



the Lower Receiving Plate (12) with a thin 
piece of tissue or cigarette paper under each 
type. The type must be spaced far enough 
apart so that a type will be under each end 
of the Upper Receiving Shoe (20). Press 
the shoe down onto the type by hand and 
tighten the knurled head screw, that holds 
it in place, very firmly with the pin wrench. 
The tissue paper is put under for the pur- 
pose of preventing the type that is sub- 
sequently cast from sticking between the 
Upper and Lower Shoes, because the types 
cast will be hot and consequently slightly 
larger in size than after they have cooled. 
The tissue paper will pass out of the Re- 
ceiving Shoe automatically as the types are 
being cast. 

After the Upper Shoe has been adjusted, 
and before casting, bring the Vertical Mold 
Blade down into its lowest position; then 
turn the Knurled Head Screw (5) so as to 
bring the lug on the side of the upper end 
of the Vertical Mold Blade Bridge (6) 
down tight on the highest part of the Upper 
Receiving Shoe (20). Now turn this same 
knurled screw backward a half turn, then 
tighten the fillister head locking screw. 
This must be done so that the coil spring 
which is located inside the upright, portion 
of the Vertical Mold Blade Bridge (6) will 
have just enough tension to hold the type 
firmly between the Vertical Mold Blade 
Support and the Bridge as it is carried up 
and down. 

It is very important that all of the work- 
ing parts of the device be kept very clean 
because the least bit of dirt or metal ac- 
cumulation will cause trouble. Also be sure 
that you get a full solid cast of the first few 
types that are started through the Re- 
ceiving Shoe. If these types are hollow the 
pressure of the extractor will cause them 
to be started improperly through the Re- 
ceiving Shoes and the succeeding types will 
follow in the same manner. 

Dressing Knives 

There are four Dressing Knives. One is 
located in the Upper Receiving Shoe (20), 
one in the Lower Receiving Plate (12), and 
two are attached to the Vertical Dressing 
Knife Holder (26). 



The Dressing Knives in the Upper Re- 
ceiving Shoe and Lower Receiving Plate 
have three teeth each. They are adjusted 
so the end of the teeth are even, or level, 
with the flat sides, or inner surfaces, of the 
Receiving Shoes (12 and 20). For Kerning 
type knives with beveled teeth, having the 
proper angle for trimming or undercutting 
the character on the type, are furnished. 
These are called Kerning Knives and are 
adjusted in the same way as the Dressing 
Knives. 

The two Vertical Dressing Knives (27 
and 28), attached to the Vertical Dressing 
Knife Holder (26), have two teeth each. 
One of these knives is fastened to the right 
side of the Holder and need never be moved, 
regardless what size types are to be dressed. 
The other, which is the adjustable knife, is 
held in position by two long screws that 
pass through tw T o holes in the shank of 
said knife into two tapped holes in the 
shank of the stationary knife. The two 
screws hold the Space Plates (29), as well 
as the Adjustable Knife, in position on the 
Holder (26). For Kerning type the knives 
with beveled teeth must be used and ad- 
justed the same way as the Dressing 
Knives. 

Bearding Type 

When the printing face of the character 
projects set-wise or body-wise beyond the 
stem of the type it is said to beard and the 
projecting portion must be "bearded". 
This means that the sides of the character 
must be trimmed parallel with the body, 
while the adjacent type must have the 
shoulder of the body cut or trimmed off 
square, so that it does not, when set up, 
foul the side or bottom of any character 
to which it may be adjacent. One of the 
two Bearding Knives is attached to the 
Lower Receiving Plate (12) and the other 
to the Upper Receiving Shoe (20). Each 
has two teeth and each must be adjusted to 
trim or beard the shoulder end of the body 
and the sides of the character. To do this 
proceed as follows : 

Remove the Upper Receiving Shoe (20) 
and cast one type by hand. Take the type 
out of the Vertical Carrier and place it on 
the Lower Receiving Plate (12) so the 



THOMPSON TYPE MACHINE COMPANY 



53 



/^\ 



character overhangs the lower Bearding 
Knife (13) ; adjust this Knife so the upper 
ends of the teeth will trim off the bevel or 
inclination on the upper side of the charac- 
ter without cutting into the face of the 
type. 

Now place the type on the Upper Re- 
ceiving Shoe (20), with its nick fitting over 
the nick in the Shoe, and adjust the Upper 
Bearding Knife (21) in the same manner 
as the Lower Bearding Knife (13). 

Put the Upper Receiving Shoe (20) back 
on the machine and make all adjustments 
thereof as explained in the second para- 
graph under the caption, "Adjustments". 
When the knives (13 and 21) are adjusted 
as explained above they will trim off the 
shoulder end of the type and beard the 
sides of the characters so they will fit closely 
together without fouling one with the other. 

When changing from one set-wise size of 
type to another, the number of points of 
the set-wise size of type to be dressed must 
be made up by placing the required number 
of Space Plates (29), to equal the width of 
the type in points, between the shanks of 
the two Dressing Knives (27 and 28). (The 
figures stamped on the Space Plates desig- 
nate their thickness). The remaining Space 
Plates must be placed on the other side of 
the Adjustable Dressing Knife so all the 
Space Plates are always on the Vertical 
Dressing Knife Holder (26). 

Turn the machine over slowly by hand 
for several revolutions to make sure that all 
adjustments work freely. Then lock the 
Pot into casting position and cast a few 
type by hand so as to be sure all adjust- 
ments are properly made. Now turn on the 
power and operate the machine in the usual 
manner. 

Adjusting Vertical Dressing Knives 

If at any time the sides of the type show 
that the Vertical Dressing Knives are cut- 
ting more on one side than the other it 
indicates that the Extractor Slide (14) is 
not correctly set. To remedy this proceed 
as follows : 

Remove the screw that holds the Vertical 
Dressing Knife Link (35) to the Vertical 
Dressing Knife Lever (37). The Vertical 



Dressing Knife Holder (26) can then be 
moved up and down by hand. Next, remove 
the Upper Receiving Shoe (20). Now place 
a type of the set-wise size to be dressed on 
the Type Receiving Plate (12) and turn 
the Hand Wheel over by hand until the 
arrow on Cam (49) points straight down. 
The type must be held firmly against the 
Extractor so as to take up any lost motion 
there may be in the different parts. Then 
bring the Vertical Dressing Knife Holder 
(26) down to the type by hand, being sure 
that the Space Plates between the Vertical 
Dressing Knives equal the set-wise size of 
the type. Loosen the nuts on upper and 
lower ends of the Connecting Rod (59) and 
turn the Connecting Rod, either to the right 
or to the left, until the Extractor Slide 
brings , the type in proper position for 
dressing even on both sides. 

Now replace Upper Type Receiving Shoe 
(20) and the Vertical Dressing Knife Hold- 
er (26) as previously explained. 

When replacing the Trimming Attach- 
ment care must be taken to put the Trim- 
ming Attachment Cam (49) correctly on 
the left outside end of the Cam Shaft. This 
Cam (49) has an arrow marked on its out- 
side flat side. When putting it in position 
first turn the Cam Shaft of the machine 
in the clock-wise direction until the Ver- 
tical Mold Blade has just reached its low- 
est, or normal, position. Place the Cam on 
the end of the Cam Shaft by putting the 
two pins which project beyond the inside 
flat side of the Cam into the two holes in 
the shaft so the arrow on the outside, flat 
side, of the Trimming Attachment Cam 
points upward. 

Removing Trimming Attachment and Ad- 
justing Machine For Casting Spaces 
and Quads 

When a Thompson Typecaster is shipped 
with the Trimming Attachment, all adjust- 
ments for casting and kerning type are cor- 
rectly made. Samples of types cast and 
trimmed will be found in the Receiving 
Shoe on the machine. 

We suggest that the operator closely 
study the movements of the different parts 
of the Trimming Attachment before mak- 



Ot" 



THOMPSON TYPE MACHINE COMPANY 



ing changes to another size body, or before 
removing it from the machine. 
; To remove the Trimming Attachment 
proceed as follows: Swing back the Metal 
Pot and remove the Nozzle Plate. Take 
out the screw that connects the Vertical 
Kerning Knife Link (35) to the Vertical 
Kerning Knife Lever (37) and put the 
screw back into the hole in the Vertical 
Kerning Knife Lever (37) so it will not be 
lost; then lift out the Vertical Kerning 
Knife Holder (26). Now take out the 
Knurled Head Screw (696), which holds 
the Upper Receiving Shoe (20) in position 
on the Mold Stand and remove the Receiv- 
ing Shoe (20). Remove the Vertical Kern- 
ing Knife Spring (42) and Cam Lever 
Spring (54), take out the Hexagon Head 
Screw that holds the Vertical Kerning 
Knife Lever (37) in place and remove the 
Housing Cover (48) by taking out the four 
screws that hold it to the Vertical Kerning 
Knife Lever Housing (47) and lift out the 
Lever (37) and Lever Link (41). The two 
flat head screws that hold the Housing (47) 
to the side of the machine Base must then 
be taken out with a good screw driver and 
the Housing (47) removed. With a good 
screw driver now remove the Vertical 
Kerning Knife Spring Stud (43), than take 
out the Hexagon Head Screw that passes 
through the end of the Cam Lever (50), 
and the Hexagon Head Screw that holds 
the Bell Crank (61) in position and remove 
the Cam Lever (50) and Bell Crank (61), 
both of which are held together by the 
Connecting Rod (59). 

The Stationary Jet Breaker (64) should 
then be removed by taking out the two 
flat head screws that hold it to the Mold 
Stand. Then draw the Extractor Slide 
(14) out of the Receiving Plate (12) and 
take out the two screws that hold this Plate 



on the Mold Stand so that Receiving Plate 
(12) may be removed from the machine. 
The Cam (49) is then removed by taking 
out the screw that passes through it into 
the end of the Cam Shaft. Be careful to 
put all the Trimming Attachment parts into 
a box of some kind so nothing for the 
equipment becomes lost. 

Now take out the Vertical Mold Blade 
with its type support and Top Bridge 
which are all fastened together, and put in 
its place the plain Vertical Mold Blade ; but 
do not disturb the Type Mold as this may 
be left in position when changing the Ver- 
tical Mold Blade. 

Fasten the regular Jet Breaker to the 
Pump Lever Link with two screws in the 
place provided for it on the Pump Lever 
Link. 

Put the Lower Type Receiving Plate and 
Upper Type Receiving Shoe in place on 
the Mold Stand. The quad Trimming 
Knife, which is attached to the Lower Type 
Receiving Shoe must be in place on said 
Shoe before it is put onto the Mold Stand. 

When a machine is equipped with Quick 
Change Foundry Style Matrix Holder, this 
must be removed from the Matrix Carrier 
as explained in a preceding article under 
the caption, "To Replace Foundry Style 
Matrix Holder with Holder for Space and 
Quad Matrices". 

Select Space and Quad Matrices required 
to make up the Setwise size of the quads, 
that you wish to cast (all space and quad 
matrices are stamped wth figures designat- 
ing the body and setwise size for which 
they are intended) ; place these matrices in 
position in the carrier, hold them in place 
with the Space and Quad Matrix Clamp, 
place the Carrier in position on the machine 
and make all adjustments as explained 
under "Quad and Space Matrices"-

us with all the data that appears on the name plate of the old motor. When 
ordering a new one, give voltage and tell us whether current is D. C. or A. C. 
If it is A. C, we must know whether current is single, double or three phase and 
the frequency in cycles. 

Motor Brackets — When ordering duplicate or new motor brackets be sure 
to furnish all data on motor as called for under heading "^ Horse Power Motor." 
The dimensions of motors for various current requirements differ and if we are 
to furnish brackets of the proper height we must have detailed information con- 
cerning the motor with which they must be used.
